Nikita Gourianov, a physicist at Oxford university claims about the field of quantum computing

Nikita Gourianov, a physicist at Oxford university claims about the field of quantum computing and the scientists who work in it. Quantum computing is often portrayed as an up-and-coming technology whose eventual impact will only be rivaled by artificial intelligence. Quantum computing reached the mainstream, leading to greed and misunderstanding taking hold and the formation of a classical bubble. The quantum computing industry has been led astray by greedy quantum physicists who've hyped up the tech's possibilities in order to rip off VCs. There is no evidence that even quantum chemistry calculations can be significantly sped up with quantum computers.

Quantum physicists are money mongers:

Quantum computing appears, inexplicably, to be that they won't be very useful for cracking quantum-resistant encryption. It is only a matter of time before a fully-functional quantum computer will appear and do everything from revolutionizing drug development to cracking internet encryption schemes. There were just too many problems to overcome in order to make computers affordable and useful for personal use.

Quantum computing firms are actually earning any real money. Rigetti, IonQ, and D-Wave, these three jointly still have a market capitalization of $3bn, but combined expected sales of about $32mn this year. Quantum computers will help their business as opposed to genuinely harnessing any advantages that quantum computers have over classical computers. However, the commonly forgotten caveat here is that there are many alternative cryptographic schemes that are not vulnerable to quantum computers.

According to Guryanov's article, the real problems started in the 2010s after investors started noticing the hype around quantum physics. Their quantum-inspired approach provides a pathway toward conducting computational fluid dynamics on quantum computers. today's quantum computing systems don't work well enough to replace classical computers for many useful functions. the quantum computing industry has yet to demonstrate any practical utility, despite the fanfare.
