Precisely. That's why I said 'Net Fit Block Size'. The processing speed to match the communication speed to keep the thing away from recentralization death spiral. Back in 2010 when Satoshi imposed the block size limit - to avoid the infinite block menace first, but more to keep blocks small enough so to not choke the net ... afair Gavin Andresen spoke about automation of block sizing. Extremely meaningful goal btw, as far as it is possible to be done on-chain, i.e. without reliance on off-chain stream of info, prone to manipulation. ( One of the ways would be to , say, tie up block size maximum with difficulty or transactions flux. ) Moore's law inevitably increases both the node and net capacities, so it'd be nicely unwinnable arms race. On Moore's law specifically - my current understanding of physics is that it is inexorable. For (simply) the Planck scale as much as unreachable as the alphabetical example - speed of light, or the absolute zero. They are asymptotic 'boundaries'.

As long as it’s profitable I don’t see why everything won’t get faster. There is too much money to be made by getting more efficient.
