You don't think his comment is "an assumption put forward for the purposes of discussion"? That seems a fairly low and generic bar for a comment to reach...
Truthfully, I hold those ideas a little more confidently than purely "for the purposes of discussion", but I suspect you at least understand that the real-world usage of "hypothesis" is quite broad.
I'm kind of tickled at the idea that a "hypothesis" is some hyper-specific thing with trappings of "credibility", and that anything less would be an insult, like we're not all just a bunch of nerds arguing on the internet. It's also kind of sad, though. This is why computer people need liberal arts education.
Yeah, hence why I asked… otherwise anyone on HN, including me, could say their opinions are hypotheses too, to be taken just as seriously as the parent’s.
Sufficient chimpanzees with keyboards, or an LLM, can also type out every comment you’ve ever written, including the last few.
