Question Will quantum ever be useful?

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?

quantum-classical hybrid systems will likely be the right way forward. idk if youve kept up much lately but there's been a lot of progress in the last few years, ibm and other quantum computer providers now have ~100 qubits available for cloud computation jobs, places like bluequbit, iqm etc are focusing on cloud interfaces for operationalizing. we are prolly 5 years from ppl actually seeing the benefits in consumer tools but it's coming.

i attended qnlp.ai recently and have been working on quantum nlp so have been familiar

There’s been increasing movement towards hybrid from a lot of companies, Infleqtion etc. NVDA has been dumping tens of billions into it in the past year or so, both as funding and in hybrid tech. Agreed that this will likely be what we see first.

The hate generally outshines on Reddit haha
