There's some pretty cool problems in quantum systems like chemistry that even a classical supercomputer would not be able to solve
This could have a very positive impact on fields like medicine
I am not saying what quantum computing is or isn't doing. Contrasting quantum computing and AI is like comparing... digging a hole and shovels. "While digging a hole is useful, these shovels are even better than hole-digging!" It's nonsense sauce. If quantum computing can be useful at AI tasks, then quantum computing won't replace AI, we'll be doing AI on quantum computers. This is just marketing mumbo jumbo to convince some C-suite type that doesn't know a thing about data science to say, "Why are we still using AI and not this quantum thing IBM has? Quantum is better than AI!"
Yes, yes, real AI died in the AI Winter because the settlers didn't have enough parenthesis to last until spring, it was all very tragic, and now we're all just stirring the pile of linear algebra until the results look good. [1] But that doesn't make IBM's marketing copy any better. And IBM loves making grandiose claims that don't work out in practice. [2]
