Is Deep Blue superintelligent or not?

Question

When AI has some narrow domain, such as chess, where it can outperform the world's human masters of chess, does it make it a superintelligence or not?

Answer 1

There are three typical use cases for the phrase 'superintelligent':

1. Something that is at least as smart as a human for every task.

2. Something that is smart enough to improve itself on a fundamental level.

3. Something that is smarter than a human at a single task.

Most uses that I see are definition 2, but the other two are also somewhat common. I typically follow I. J. Good and use ultraintelligence for the first definition. (There are lots of arguments that something that fits definition 1 is likely to fit definition 2 as well, but this doesn't seem to be logically necessary.)

Obviously, Deep Blue only counts for definition 3.
