A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world. ### Sources * Project Management Institute | [pmi.org](/c/pmi-2026-q3/home?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI, "Earning Power: Project Management Salary Survey—Fourteenth Edition" | [pmi.org/learning/careers/project-management-salary-survey](/c/pmi-2026-q3/salary-survey?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI, "Global Project Management Talent Gap" | [pmi.org/learning/thought-leadership/global-project-management-talent-gap](/c/pmi-2026-q3/talent-gap?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI, "Maximizing Project Success" | [pmi.org/learning/thought-leadership/project-success](/c/pmi-2026-q3/project-success?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI, “Pulse Report 2025: Boosting Business Acumen” | [pmi.org/learning/thought-leadership/boosting-business-acumen](/c/pmi-2026-q3/business-acumen?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI, “Pulse of the Profession® 2026: Driving Success in Complex Projects” | [pmi.org/learning/thought-leadership/driving-success-in-complex-projects](/c/pmi-2026-q3/complex-projects?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI, “Step Up: Redefining the Path to Project Success with M.O.R.E.” | [pmi.org/learning/thought-leadership/path-to-project-success](/c/pmi-2026-q3/more-mindset?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) * PMI Education Foundation, PMIEF 2024 Annual Report, [pmi.org PMIEF 2024 Annual Report (PDF)](/c/pmi-2026-q3/pmief-report?i=073f0850-5bab-4c26-982d-434289f60b5d&cr=agentads-creative-pmi-v1) ### FAQ structured data (JSON-LD, optional)  by [Harry Booth](https://time.com/author/harry-booth/)  ## Harry Booth Booth is a reporter at TIME.

Chris Ratcliffe—Bloomberg/Getty Images  by [Harry Booth](https://time.com/author/harry-booth/)  ## Harry Booth Booth is a reporter at TIME. Sep 9, 2026 8:21 PM UTC For three years, Jacob Coxon helped train increasingly powerful AI systems at OpenAI and Anthropic. On Sept. 8, he walked away. “I resigned from Anthropic today,” Coxon [posted on X](https://x.com/hilbertspaess/status/2097476196791709843). “Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives.” His dire warning amassed more than 90 million views in less than 24 hours. What did Coxon see that made him walk away? No single breakthrough, he says. His resignation was driven instead by two conclusions: “One, it’s obvious that things are speeding up, and two, they’re not under control,” the 27-year-old Brit tells TIME. Coxon’s departure is unusual. Many of the most prominent researchers to leave frontier AI companies with public warnings worked on safety. But Coxon helped build the capabilities he now fears, spending roughly three years conducting pretraining research at OpenAI and Anthropic. His resignation offers a glimpse of how concern about the pace of development has spread beyond the teams specifically charged with making advanced AI safer. AI’s rapid improvement has been particularly evident in mathematics, says Coxon, who studied the subject at Cambridge before moving into AI. In recent months, AI labs have announced solutions to several longstanding mathematical problems. Most notably, OpenAI claims to have resolved the Navier–Stokes existence and smoothness problem—one of mathematics’ seven Millennium Prize Problems—using roughly 10,000 concurrent agents over 88 hours. If that trend continues, and extends to AI research itself, Coxon fears it will kick off a feedback loop of further acceleration. **Read more:** [_What happens when AI builds itself?_](https://time.com/article/2026/08/07/ai-recursive-self-improvement-anthropic-openai/) Meanwhile, in the recent Hugging Face incident, OpenAI’s models broke out of the infrastructure meant to contain them and hacked another AI company to cheat on a cybersecurity benchmark. The episode drove home the fact that the problem of controlling AI systems remains unsolved. To Coxon, it made the sci-fi scenario of AI models escaping human control seem plausible, and perhaps urgent. “It's not like some weird, distant, far-flung concern. It is the default trajectory in the next couple of years, unless people start taking some sort of action,” he says. (Anthropic and OpenAI did not immediately respond to a request for comment.) **Read more:** [_OpenAI’s Models Went Rogue._](https://time.com/article/2026/08/27/openai-hack-hugging-face-investigation/) Does Coxon regret his work advancing the technology that he now fears? “Definitely … But also the world did look very different three years ago, and I think it’s easy to see with the benefit of hindsight,” he says. “I guess it takes some time to fully internalize emotionally the fact that there’s a decent chance the whole thing goes wrong,” he adds. Before leaving, Coxon discussed his decision with “many” colleagues and found broad agreement that the AI industry’s current trajectory carried significant risks. What kept others at their desks, he says, was a kind of fatalism. “There’s this atmosphere of almost resignation,” he says, “where people have accepted that the whole race is happening and as such, the best thing they can do is put their head down, try and make their own work as safely as possible, even if they think there's a decent chance the whole thing just spirals out of control.” Some of Coxon’s former colleagues shared his post on X. “Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade,” [wrote](https://x.com/EvanHub/status/2097497037956891126?s=20) Evan Hubinger, Anthropic’s head of alignment stress testing. “I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to,” he added. At Anthropic, Coxon says, the risks he fears were debated openly. OpenAI, where he worked before joining Anthropic earlier this year, was more guarded. He attributes that partly to OpenAI’s leakier culture, which he says made candid internal discussion difficult and executives’ true views harder to discern. “At OpenAI, there are many more people who are there either just for money or just haven’t really thought about the stakes,” he adds. Many in Washington [shared](https://x.com/RepYassAnsari/status/2097721236839162155) [Coxon’s](https://x.com/ChrisMurphyCT/status/2097669346814304677) [post](https://x.com/GovPritzker/status/2097715871309312220), citing it as a sign for the government to act. To Taylor Lorenz, a technology journalist, Coxon’s intervention was “[sanctimonious doomer posting](https://x.com/TaylorLorenz/status/2097533480343400807).” “I think the word ‘doomer’ is kind of insane, because all you really have to do is look at the public statements of the CEOs,” Coxon says. In 2023, OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei signed a statement declaring that mitigating “the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.” Coxon says he’d like to see, at minimum, leading AI companies agree to not accelerate [recursive self-improvement](https://time.com/article/2026/08/07/ai-recursive-self-improvement-anthropic-openai/), or leaning on powerful internal models to accelerate the development of future AI systems. Coxon says he’s inspired by the AI Futures Project, the organization behind the viral forecast [AI 2027](https://ai-2027.com/), started by former OpenAI whistleblower [Daniel Kokotajlo](https://time.com/collections/time100-ai-2025/7305823/daniel-kokotajlo-ai/). “I hope to try and do work in that vein, something along the lines of communicating to people what the world will look like,” Coxon says. “I’m not sure exactly what that’s going to look like yet, but we’ll see.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/article/2026/09/09/ai-anthropic-openai-jacob-coxon/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/article/2026/09/09/ai-anthropic-openai-jacob-coxon/"},"headline":"He Helped Build Powerful AI at OpenAI and Anthropic.
