AI agent diversity will be on the upswing, so we've got that going for us. We'll also be more insulated from the climate by virtue of all of our bodies being lashed together into a machine and flesh lattice controlled by the executive overmind.

What remains of humanity will be safely cocooned inside the biomechanical membrane between the chaotic outside world and whatever environment the compute prefers. The perspiration of its leviathan breaths and a circulatory system that pumps coolant will ensure the temperature differential.

Like how single cell organisms were engulfed into multicellular organisms, so shall our descendants be engulfed. Countless immobile interconnected bio-systems with humanity as its ancestor. They'll less adaptive than us but more optimally specialized. I wonder how recognizable humanity would be when we're tessellated into one large interconnected amalgamation. Furthermore, I wonder how many generations we have left where we'll still need a face and outward looking eyes. Skin cells don't need flagella after all.
