Former Ripple Vice President Yoshikawa Reacts to Viral Manifesto From Claude AI Developer

The public resignation of leading AI developer Jacob Coxon from Anthropic has caused a stir among international technology investors. The incident drew the attention of Emi Yoshikawa, Ripple’s former vice president of global operations, who is now involved in venture capital projects.

On her X account, she quoted an insider and wrote that the researcher’s post was rapidly gaining traction, while developers inside the company genuinely believe that artificial intelligence could destroy humanity within just a few years.

What the developer who quit revealed and why the fintech market is discussing his post

Jacob Coxon spent the last three years specializing in neural network pretraining, working at both OpenAI and Anthropic. In his resignation manifesto, he directly accused the leadership of both laboratories of engaging in an irresponsible race to create self-improving superintelligence.

“I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives,” Coxon stated.

According to the researcher, specialists developing advanced models such as Claude privately acknowledge the technology’s existential threat. Coxon highlighted the difference between the companies’ approaches: while many OpenAI employees still do not fully understand the scale of the risks, those at Anthropic recognize the danger but continue to accelerate development out of fear of losing the competitive race.

Yoshikawa’s public analysis of Coxon’s manifesto highlights a new trend: the fintech market and venture capital funds have begun to treat internal turmoil at AI laboratories as a direct financial risk. When a former senior Ripple executive with ties to international investment circles amplifies panic among developers, it damages investor confidence more severely than any regulatory forecast.

For Anthropic and OpenAI, such insider revelations are not merely a blow to their reputations but a genuine threat to their valuations ahead of new funding rounds.

As a systemic solution, Coxon urged fellow engineers to reflect on their work and called on regulators to establish international agreements governing the pace of technological development, including a temporary ban on advancing AI’s core capabilities.
