Ibian, doing more of the same stuff in the same way is the least intelligent possible way to scale. And in fact, attempting to do that in bitcoin actually causes problems to increase more rapidly than benefits.
(Do I have to explain why larger blocks create runaway centralisation?)
It can be done pretty much literally by changing one number, it has the least potential complications and has to my understanding already been tested with no meaningful complications.
This whole thing is stupid. It's not one or the other. Do both.
