@Bitcoin Mechanic podcast on the topic. You can way back before bip110 or core30 was as pretentious and compare his thoughts with others like Shinobi or Gloria Zhao on WhatbitcoinDdid.
Or listen to Mechanic’s (aka grassfedbitcoin) most recent podcast just to get a feel for who he is.

You have to start somewhere.
