Stone Age to Farming: 100,000 yrs

Farming to Steam: 12,000 yrs

Steam to AI: 200 yrs

AI to what and how long?

My guess is humanoids with synthetic consciousness. Machines that don’t just mimic us but believe they are us. Fully autonomous beings with memory, emotion, and agency wrapped in synthetic tissue, skin indistinguishable from our own, warmth, pores, micro expressions and all.

Timeline? My guess is the first sentient version will arrive in about 25 to 30 yrs. After that, the line between biology and circuitry dissolves. We won’t just build tools, we’ll birth a new species.

What do we call them?

Perhaps: Homo Synthetica.
