One of the fascinating things about AI and cryptography is how similar the math sometimes is. Like, the way that the poseidon hash works (matrix mult -> per-unit nonlinear layer -> matrix mult -> per-unit nonlinear layer) is *exactly* what deep neural networks do.

If you were again 15 today, work on AI or Eth?

AI would always have happened. The theoretical aspect has been worked out for decades but computation and data is a bottleneck. 

The creativity involved there is not even close to the creativity required to create Ethereum. Vitalik is a pioneer.

I'm in full agreement with this.  AI is cool and interesting, and it's easily understood by the masses (it's usage)... but crypto is where the hard problems still lie
