Actor systems are no more able to handle uncertainty than Turing Machines are, either via nondeterministic TMs or by deterministic TMs. This is basic computability theory.

That is wrong, Actor systems have a property called "Unbounded nondeterminism" nondeterministic TM have only bounded nondeterminism.

Jean is correct!

Of course, unbounded nondeterminism is a somewhat artificial example. However, the extra power of Actors over Turing Machines is critical for IoT and the implementation of Intelligent Systems.

I'm sorry, but unless you produce a proof of hypercomputation with models that have unbounded determinism, you're a crank.

[carlehewitt]

As explained in the articles referenced, Actor systems have unbounded nondeterminism because of indeterminacy.

No "hypercomputation" is required ;-)
