I was taught the universe was a computer in 3 different college courses 25 years ago. Not exactly a revelation.

"According to the best physics, the universe: isnt programmable; doesn't evolve deterministically; isnt described by functions over integers; isn't electronic; doesnt transmit power through programmable operation; isn't abstract; doesnt have causal powers through mere arrangements of parts; .. and so on."

You can't say any of these things because electronic computers exist within the universe, but I get what your point is. That said, there are physicists beginning to assume the universe IS a computer and work forward from that assumption.
