We would need 150 quadrillions of Petabytes to store Satoshi in the blockchain

The average volume of the brain is around 0.001234 m3. That is, 0.1234% of a cube with one meter.
If we consider cubic picometers (10e−12 m) close enough to the Plank scale in order to 100% digitize a human brain and assuming that each cubic picometer would need one bit of memory to be stored in a digital format, we would need 2 to the power of 1.234e+33 bits since we have about 1.234e+33 cubic picometers to digitize with zeros and ones. That is: 154,250,000,000,000,000 Petabytes, or about 150 quadrillions of Petabytes.

Would we need about 150 quadrillions of Petabytes to store a digital brain version of Satoshi's brain? Could one day have a blockchain that could store that amount of data?

Please do check all my calculations and estimations and if you can come up with different ones please kindly show yours.

Your calculation is wrong, because that's just storage for one copy of a human brain. The whole point of blockchain is to store the same data duplicated on many computers to have no single point of failure. So in this case you'd need to multiply this number by thousands or tens of thousands.

But why would anyone want to store a human brain on blockchain? Blockchain is only good as an append-only live database, not a general use database.
