On: A warning about 'model welfare'

[budman1]

Those non-deterministic results are exceedingly rare.

[lioeters → budman1]

As long as the machine is part of the larger universe, and not completely isolated in its own bubble of space-time (an impossible situation, an object without an environment) - it cannot be purely deterministic because of the fundamental nature of physics.

[mitxela → lioeters]

So your theory is that arithmetic is nondeterministic because very rarely a calculator will say 1+1=3.

[lioeters → mitxela]

Arithmetic is deterministic, because it is abstract. A calculator or computer is not, because it is physical and exists in a non-deterministic universe. But with error correction, etc., it's deterministic enough for practical purposes. For more in-depth explanation, start with https://en.wikipedia.org/wiki/Indeterminism

[qarl → budman1]

When human input is involved, like I described elsewhere, it happens frequently.
