This guy knows his byzantine general's problem.

If POS worked, great.

I wouldnt trust it for a half decade of use.

IOHK has many conference accepted peer reviewed research papers that show that proof of stake has equivalent security properties as proof of work.

A peer reviewed paper saying WPA2 is secure also exists. That clearly didn’t make it so.

Only if we enumerate all possible attack vectors, and prove resiliency against these, is the proof as general as you claim. The difficult part — as the WPA2 paper shows — is the former.

How do you know when you’ve enumerated all possible attack vectors?

That's a good question. It's impossible to prove that anything besides math itself is absolutely true but we can say that for all known knowledge what is in this paper is true and secure. Unless some new discovery is made the papers show that proof of stake has similar mathematical security properties as proof of work.

> conference accepted

sure.

> peer reviewed

not so sure.

Bingo.
