It’s the same story for quantum computing

Unless I've missed some developments, quantum computing's applications are somewhat-niche. Yeah, it's a new field, but I am not sure that it's something that I'd be incredibly worried about (at least from an economic standpoint; from a military communications standpoint, maybe it matters, as there are some important applications there).

Yeah:

Quantum algorithms provide speedup over conventional algorithms only for some tasks, and matching these tasks with practical applications proved challenging. Some promising tasks and applications require resources far beyond those available today.[121][122] In particular, processing large amounts of non-quantum data is a challenge for quantum computers.[85]

I mean, it's cool in that in involves interesting physics and engineering stuff maybe, but I'm not sure that it's that interesting economically.

Like...I think that blockchain stuff is technically interesting too. But...there are only so many realistic applications, and people have tried to use it in a lot of cases where I don't think that it's all that useful.
