I tend to think everything should stay out of layer 1. It should all be layer 2. I've been saying every open ended smart contract platform is doomed to fail. We have 3 second block times. The amount of shit we can do is finite because of that. I'd move all of this to layer 2s. it doens't have to be hive-engine. let there be competition, but keep layer 1 as clean as possible.
