Many people mocked me many pages ago for my concern that the block size could not simply scale exponentially for the next 20 years, but I still believe we are reaching the limits of physics and any further significant exponential type gains in computing power beyond asic will likely take us beyond the singularity. I just hope our new synthetic overlords accept bitcoin. (Ok, yes, I've been watching too much humans (tv show))
Block size MUST scale exponentially whether it's simple or not. A crypto with a block size limit is analogous to an Internet with a bandwidth limit of 56K modems. No video. No VOIP. Vastly more limited functionality. It may be hard, but don't fucking tell me it's impossible. Some other crypto will do it if we don't.
