Then computationalism is false. But what are your evidence for a
*primary* physical universe. That is an axiom by Aristotle, and I
believe animals are hard-wired to make some extrapolation here (for not
doubting the prey and the predators), but there are no scientific
evidence for a *primary* physical object.
There is no scientific evidence for a universal dovetailer either. And
so far there is no evidence that it can produce anything like the
physical universe we observe. Primary physicality is a lot simpler.
Occam's razor to the fore....
The UD works a bit on the first execution, then a bit on the second
execution, and then comes back on the first, then the second, then the
third, and then come back to the first, etc.
In that way, the UD executes all computations, including all those who
never stop.
Yes, I had misread how that works. But who wrote the programs it
executes? Who wrote the scheduler? Seems a lot simpler to have a primary
physical universe. Then all you have to do is explore it.
