Seems like it would give a large performance penalty. I don't get it.
One instruction set computers (OISC) are more than a joke, I suppose, but I didn't dig far into theoretical computer science and can't say, what's important about them.
I read a comment the other day, that stipulated neurons would be akin to massively parallel single instruction computers.
They're for highly parallel programable SIMD number crunching. The OISC would allow for easily fabricating a whole heaping bunch of ALUs.
At about 7 minutes in he is chatting about it but all is a good watch - could only find the YT link sorry
