It is only allowed in unsafe blocks. As long as the unsafe blocks are few and well understood then Rust programmers can contain this to a small well defined portion of a program.
I can't tell if this comment is sarcasm or not. If you let AI run commands you don't understand (especially in production) you may end up with some nasty surprises.
The ultimate piece is not revenue but profit. At some point these enormous investments will have to be earned back. Good luck with that when open weight models are also continuously improving, have cheap providers and for many are already very usable.
Yea I get that, I still wouldn't want to invest a serious amount of time on a product to build on such a platform. Best of luck though maybe it still works as a business.
Vendor lock-in with a monthly subscription where the price can change at any moment or the company may disappear along with your product. I wouldn't build my business on that.
The open models cannot be taken away. Anyone with the right hardware can host these. Unlike the API/subscription services where you can be banned from, may have drastic price increases or reduction of their limits.
The open models may not be as great but maybe these are good enough. AI users can switch when the prices rise before it becomes sustainable for (some) of the large LLM providers.
