I love to show that kind of shit to AI boosters. (In case you're wondering, the numbers were chosen randomly and the answer is incorrect).
They go waaa waaa its not a calculator, and then I can point out that it got the leading 6 digits and the last digit correct, which is a lot better than it did on the "softer" parts of the test.
You forget a few major differences between us and AI makers.
We know that these chatbots are low-quality stochastic parrots capable only of producing signal shaped noise. The AI makers believe their chatbots are omniscient godlike beings capable of solving all of humanity's problems with enough resources.
The AI makers believe that imitating intelligence via guessing the next word is equivalent to being genuinely intelligent in a particular field. We know that a stochastic parrot is not intelligent, and is incapable of intelligence.
AI makers believe creativity is achieved through stealing terabytes upon terabytes of other people's work and lazily mashing it together. We know creativity is based not in lazily mashing things together, but in taking existing work and using our uniquely human abilities to transform them into completely new works.
We recognise the field of Artificial Intelligence as a pseudoscience. The AI makers are full believers in that pseudoscience.
