We know the approximate processing power of brains (O(1e16-1e17flops)
This is still debatable, see Table 9 is the brain emulation roadmap https://www.fhi.ox.ac.uk/brain-emulation-roadmap-report.pdf. You are referring to level 4 (SNN), but level 5 is plausible imo (at 10^22) and 6 seems possible (10^25), and of course it could be a mix of levels.
