It'd be fascinating to know if this is helping or hindering programmer productivity. None of these new capabilities seem to be step changes (all the oomph for programmer productivity that I've seen have been IDE tooling, LLMs and GPUs). I'd be impressed if they even managed to be incremental changes - in this case a vector API sounds nice enough gor example but the projects that need this must be on the margins.
These changes come with costs - tutorials obsoleted, version fragmentation introduced, huge new surface areas for bugs and security problems. Most of these languages became popular without fast release cadences (or in spite of them, Python 3 looking at you). It is quite amazing that none of them have decided to leave well enough alone. Is it the classic of programmers not being able to defend that position against people with ants in their pants, or is there a genuine community will to keep revising this stuff?
Surely there has to be some popular language where the custodian would think it is good enough to set in stone bar hardware-forced updates.
