The folks who actually go work in the field, understand the structural problems, the costs/benefits, and the long slog to bring successful treatments to patients are skeptical. But we're still more than happy to be proved wrong- if Anthropic (more than OpenAI) is working on life sciences and drops some amazing information that transforms cancer care with massive positive results, we all win.
Do we all? Or does anyone with enough money to pay for Anthropic's IP, win? Nothing states that Anthropic/OpenAI/... have to share information they have generated. As the crunch for income becomes real, I doubt valuable things will remain free.
If they succeeded, you can bet everybody else will be duplicating their results within 2-3 years.
