To understand the state of the quantum industry: imagine if there were 200+ companies trying to be @SpaceX the same year Sputnik made it to orbit, before @NASA even landed on the Moon.

Meanwhile, fully aware that the tech has to mature so that the market for commercial spaceflight reaches sufficiently substantial numbers to warrant high valuations, startups pitch to commercial freight companies that the future of shipping is rocket-based.

Using a quantum computer for classical data processing needs will be like renting a rocket to ship cargo. Huge engineering/energetic/budget overhead, likely won't be cost/benefit worth it, even though it will be technically faster when the technology is mature and reliable enough

The reality is that quantum tech, similarly to commercial spaceflight, will be essential for what is initially a small market, but on very long time scales will be worth trillions, and will undoubtedly be a key technology to the advancement of our civilization, no less.

For now, sending things to orbit can make some $$, but true potential of the tech is untapped.
Commercial spaceflight will take off when humans become a multi-planet species. In that case rocketry is absolutely necessary for interplanetary commerce.

Similarly, QC's are doing pilot programs in NISQ for some benefits to various co's who want to try out the space. The tech still has to lower its costs, become more reliable and powerful to yield it's full benefits.

The reality is that QC's will be truely be crucial for any engineering task where the system's physics is at the quantum limit. This includes chem/materials and many engineering tasks yet to be foreseen.

Rocketry opens up the possibility of commercial expansion and engineering to outer space.

QC will similarly expand our civilization's capabilities for commercialization and engineering deep into the quantum mechanical Hilbert space.
