Yeah it depends what you’re doing. I do a lot of circuit modeling where different subsystems need to talk to each other. The solutions are either Rcs (and a bunch of custom drop logic) or a parent struct holding all the others. Both are awkward. But in other programming domains I’ve found rust pleasant.





For 1: as a software company, they have a vested interest in ensuring that software engineers are as capable as possible. I don’t know if anthropic as a company uses this as a guiding principle, but certainly some companies do (ex Jane Street). So they might see this as more important than investment cycles.
The quality of software engineers and computer scientists I’ve seen coming out of undergraduate programs in the last year has been astonishingly poor compared to 2-3 years ago. I think it’s almost guaranteed that the larger companies have also noticed this.
