I don't think that follows remotely. It is true that it is vastly
better to interpret a column of mercury as a temperature-sensor than
a pressure-sensor or a radiation-sensor. That doesn't mean the
knows that in itself.

Computationalism does not claim that every computation is conscious.

If consciousness supervenes on inherent non-interprtation-dependent
it can supervene on features which are binary, either present or

For instance, whether a programme examines or modifies its own code is
such a feature.

Surely it comes on like a light whenver you wake up.
