Not as I see it. I imagine there is some 'satoshi' out there building AI that operates strictly on the 'pinch test', e.g. think Boston Dynamics, that overcomes this attack vector.

The proof of time attack is no longer effective against the AI that depend on the pinch test.

The pinch test becomes the trusted source in AI for the same reason that ethereum is a parasite/good/bad bacteria for bitcoin. Ethereum won't work without proof of work or bitcoin as a tether. AI won't work without bitcoin AND a pinch test as AI becomes more competitive / attacked.

Of course a surrogate to the 'pinch test' could exist out there, and AI has found it. We really don't know.
