To your virtual memory comment, the kernel can only do as it's told, but allocators can indeed tell it to shuffle pages around in virtual memory. On Linux that's `mremap` [0], and `realloc` implementations [1] use it for large enough Vecs (apparently 128kiB for glibc and musl). macOS' libmalloc will try to map new pages that extend large allocations in-place, but memcpy elsewhere if existing virtual mappings are in the way. I don't think Windows' HeapReAlloc does either, but they might reserve a larger virtual region and incrementally commit it or something to similar effect.
Yes, this is noticeably worse than the original. The first sentence is rhythmically stilted and carries less impact. "is" to "acts" is not stylistic, we're no longer discussing the nature of the object but its behaviour. 'squeezing into a generic shape' is a transformation, each piece of writing stamped into conformity, whereas 'forcing into the same generic shape' must be pulled from a grammatical reading where all writing is being packed into one box. I think "writing produced by a lazy prompt from someone" is a wash, depends if they want to further detach the writer's agency from the result (and it still isn't produced by the prompt); I do prefer "unwilling" for the original tone; but it's certainly blander writing overall. If I came across it I'd even discount some of the metaphors and choices that are still present – since it's clearly written by AI, or a marketing copywriter, I'd guess they were "polish" rather than attempting to convey any particular connotation or nuance.
