This sounded strange to me when I heard about embryonic research on this back in 2015, which even started the legal paving in this regard.

Me? I didn't like the idea (then or now), but it would be demagogic to try to fight against it, with so much wrong already existing. The difference between a neuron and a nanostructure is merely the embedded technology.

Back in the 50s and 60s, guided rockets used pigeons. Laika in space. Chimpanzees in orbit. Let's accept that we will have bio-drones and Jonny-Mneumonic style upload interfaces.
