The ironies in what you wrote here are many. It's ironic we surmise how to achieve this on Mars yet We don't seem to be thinking much or even noticing much when humans have more or less worked out how to do it on Earth, whilst there is actually a huge existentially threatening reason to do it on Earth, which again mainstream science seems unable to see or recognise, it's actually the only way out of an immediately existential situation on Earth. If only you could see it! :)
Further, on the concept of invisible branching happening between synapses, neurons or whatever, it follows that this will, and has alteady resulted in less power being used in Ai that it matters in, (ie where it is powered by finite, destructive enegy) it will already know this helps efficiency, by shorting out "unnecessary thinking" a little like we use Occam's Razor.
