Bitcoin was 1mb in 2009. Moores law shows that capacity doubles every 2 years. So for us in 2022, 64mb is equivalent to 1mb in 2009.
1) That applies to hardware transistors
only, not software.
2) The thermodynamic limits that Moore's Law CPUs like the Core 2 have encountered is the reason why you're not using a ~ 1 Terahertz CPU in 2022 and why Bitcoin network is not using 64MB blocks.
@filliponne is Simplicity dormant? I don't see anyone discussing it at all
