I am a research mathematician. I don&#x27;t think this quote is an accurate reflection of how 99% of experts feel about Mochizuki&#x27;s work. Most experts expect that if Mochizuki&#x27;s work is correct (and even if not) it contains a lot of valuable ideas. Proofs of this kind are almost never mathematical dead ends - they are difficult because they require fresh insights and these insights can always be applied to other areas.<p>Mathematics is not solely about the proof. Good mathematics is about the communication of the proof and the ideas in it. I think it is fair to say Mochuzuki&#x27;s work is not being communicated effectively. Though I am not saying the problem lies with Mochizuki alone.
