Everything you and I consider value is a fixed background from the point of view of a mind whose sole difference from ours is the speedup.
I only see them valuing that if they're also extremely neophobic in a way that, for example, would look like a human thinking that "fire" and "talking" are dangerously modern.
> Transistors pale in comparison to the interconnection density of synapses
Not so. Transistor are also smaller than synapses by about the degree to which marathon runners are smaller than hills.
Even allowing extra space for interconnections and cheating in favour of biology by assuming an M1 chip is a full millimetre thick rather than just however many nanometers it is for the transistors alone, it's still a better volumetric density than us.
(Sucks for power and cost relative to us when used to mimic brains, but that's why it hasn't already taken over).
