Of course not. There are always tradeoffs. Small blocks = more blocks = more participation = greater decentralization. Larger blocks may also slow down settlement as generally smaller blocks means more frequent blocks.
Changing the block size has absolutely nothing to do with block time.
Smaller blocks doesn’t mean faster blocks times.
Bigger blocks doesn’t mean slower block times.
Right that's difficulty
Yes that’s what makes the adjustments to keep ~10 min blocks as hash rate changes.
This makes sense. There is a trade off. It’s not so simple.
You think that’s how things work?
I was more just trying to understand his point of view.
