Tying NFTs/Web3 to some future image sensor signing tech wouldn’t be an enhancement. The public sentiment about that space has shifted rapidly while scam after scam is uncovered.

Even if some of the underpinning ideas are useful, they should be reintroduced specifically for these new use cases.

The future of this tech needs to be developed in lock step with the existing web that people actually use. This means eventual uptake by major browsers, and hopefully agreement on open standards.
