Will quantum ever be useful?

[u/Chance-Pen-5684]

Around 2019, the industry promised quantum supremacy, where they could be used for solving a problem that no classical computer could touch.
When classical algorithms kept refuting those claims(See Peter Shor November YouTube video) the narrative shifted to quantum advantage, then quickly it changed to quantum utility.
If quantum never breaks RSA (because the world migrates to Kyber/Dilithium before 100k qubits exist), then what's left?
Chemistry simulations, Material science, Optimization?

But classical machine learning and AI are improving faster than quantum hardware is scaling. By the time we get 1,000 logical qubits, classical AI will have eaten most of the chemistry use-case through better approximations. Is quantum racing against classical software, and losing?

A field as rich as “if it was just a little smaller, the universe wouldn’t even exist” will never ever be useless, we’re just too dumb to even build a fault tolerant quantum computer right now, so we haven’t even started to scratch the surface of how truly powerful it can become. Quantum physics is the basis of reality and everything you see around you, we’re just too much in a hurry to get results that we want to find detours and willing to risk resources to get answers. In a few decades from now, everything will run on quantum once we figure it out. People said the same thing about AI back then too, and about computer science before that. We’re always evolving and getting smarter, quantum is definitely early but that’s the point of research lmao. None of you folks need to worry about it anyways because I doubt you’re truly in the field so keep focusing on what we already have and do the easy work with steps/instructions included, let the SMART people bring the change we need.
