It's certainly not what modern mathematics is built upon, but it's a foundational program like any other. I don't think his views are unworthy of serious consideration.

At the end of the day if you watch the majority of his videos (which I have), he is against things which cannot be demonstrated and by definition can never be realized.

 >> Anonymous Thu Nov 23 21:51:25 2017 No.9317079 >>9316731Starting from $\aleph _0$, iterate the power set operation $\omega$ times. The cardinality of this set is $\beth_\omega$. Now take the cardinality of the set of functions from $\aleph _0$ to $\beth_\omega$. The claim is that this cardinality is greater than $\beth_\omega$.This can be shown as an easy consequence of König's Theorem, using the fact that $cf(\beth_\omega) = \omega$.So yeah, it is indeed about the cardinality of large sets. For some perspective, almost every object dealt with in classical mathematics has a cardinality below $\beth_4$.

What happened to him, how did he turn from normal maths professor to a crank?
 >> Anonymous Fri Nov 24 07:50:07 2017 No.9317885 let me quote a comment from his video on the incompleteness theorem: "Your (Wildberger's) cristal clear, consistent, free from mystery view of math, ends up being flat, dull, boring and soulless." this sums it pretty good.

I think the latter is the cause seeing rise of rise in antiscientific community, like flathead earthers, anti vaccine movements or global warming denialists
