1. Seems a bit unfair to say it has been developed since the 80's. In 80's a couple of people (e.g. Feynman) noticed that if you have a quantum simulator, you can simulate chemistry in a way that a classical computer is seemingly incapable of. But the transmon (one of the first possibly viable implementations of a qubit) was not developed until the 00's and complete control of some of these systems (e.g. transmon coupled to an oscillator, in order to make a memory) was not demonstrated until the 2010's. Life-times of quantum memories have also been growing exponentially for more than a decade (a trend that started in the 00's). 2. It is worth mentioning that by the standards of your comment, the time between conceiving of a classical computer (Babbage) and a scalable electronic computer (ENIAC and family) was about a century. 3. While ultimately there might be a "quantum winter" in the next few years because we (I work in the field) overpromised, this would not be the first time a tech that ultimately works gets disregarded for a decade or two because of mismanaging expectations (e.g. Liquid Crystal displays or neural networks, which were both developed for many decades before being commercially viable). EDIT: And yes, there are some startups with misleadingly general pitches. |

Liquid crystal displays were commercially viable 10 years before they became commercially available.
Source: my dad worked for a company that made display tubes for CRT manufacturers all over the world. He told me back in the seventies that they knew how to make TVs you could hang on the wall like a picture, but weren't making them because they were camping on a lucrative market.
