A lot of professional mathematicians are considering the idea that it might all be nonsense. Popular writing on anything technical is not always representative of what's actually going on behind the scenes.

At the same time, it's important to check the work rather than just dismissing it. Mochizuki's work isn't totally original - a lot of it is derived from existing theory. So it should be possible to validate it despite the complexity.

It's true that serious breakthroughs from individuals working alone are rare, but they are not unheard of. The real test is whether or not this work can be adapted to the rest of mathematics (or the other way around, perhaps).
