And now icebreaker is quoting a guy who's only contribution is a failed OS architecture, probably typing it from his incredibly successful linux android or windows monolithic kernel. And yes I tried minix. It crashed after a few hours.
And to add irony on top the argument actually adds ammo to block size increase crowd because lightning or sidechains will be an ESSENTIAL part of a 1MB chain. There won't be any value to users if BTC is running if lightning or SC fails because there isn't space on the chain for users.
I'm guessing ice is still in school regurgitating here the garbage his professors (who likely never worked on a million+ LOC project in their lives) feed him.
