That's an incredibly ignorant take.

LLMs are the first glimmer of artificial GENERAL intelligence (AGI). They are the most important invention perhaps of all time.

They will fundamentally change our society, our economy, and they pose an existential threat to mankind, not to mention begging existential questions about our purpose for existing at all in a world where very shortly computers will be able to out-think and out-create us.

Quantum computers are ... neat. They will allow us to solve problems conventional computers can't. They may make current encryption models obsolete ... but I haven't heard any proposed usage of them that would be even a fraction as profound as AGI.
