The line between fake and real computation is blurry though. These models are state machines which are Turing complete (if I remember a past paper correctly), and other models show capabilities of generalization also in the mathematical space. It's a long (infinite) way from running Linux, but acting as a decent (buggy) python interpreter for short programs seems possible.
Yes I agree and interestingly if you stick to basic algorithms with integers it can compute better. It’s almost like it doesn’t have true floating point capabilities but has somehow built itself integer operations correctly.
