> It's not disproven as nonsense, the paper appears to make sense

Not obviously utter nonsense, but a couple of mathematicians who have studied it have claimed to have found gaps and were unsatisfied with the resolution to those gaps that Mochizuki offered.

It's kind of like, well, LLM output. Has the right shape but upon scrutiny it seems to fall apart. Plausible-looking but probably nonsense.
