It's great at that, had a colleague run a diff through Claude and it explained how the new code was better and how the optimizations worked. Then my colleague realised they'd run the diff the wrong way round, fed Claude the new diff and Claude happily explained how the new code was better and how the optimizations worked.
You can write GPL rust code, you can also write non-gpl rust code. Gnu coreutils are gpl, if I choose to write functionality compatible with coreutils from scratch in rust I can relicense that as I please (ie not GPL) OP is postulating the driver behind rust rewrites is not for the language features but to allow coreutils functionality to be relicensed as closed source software.
I mean you can just build one. Presumably there's bugger all they can do about Voron. Slicers are open source, firmware is open source, plans are open source and there are open source controllers.
There's absolutely no obligation to be penny pinching for public companies, the leadership is obligated to act in the best interests of the company but that's about it.
The motivations and reward schemes may be very different, public company CEO may be incentivised to maximise share price for instance and that may attract the kind of psychopath that will try and maximise share price by penny pinching - equally I don't think anyone could make a serious argument that being more like Steam would be acting against the best interests of a company selling games.
This seems utterly detached from reality. From experience the theory behind times tables are taught at length then the tables are memorised for quick recall during utilisation.
I do understand that, but equally it doesn't follow the convention we use for the rest of the numbers.
