Experts agree that, while there are reasons to think that making progress in quantum computing will not necessarily be easy, there are reasons to be optimistic. Some of these reasons include the following:
- There are many smart people working on quantum computing
- Quantum computing has a push to be transparent, which will allow researchers to easily collaborate
- Recent progress has been good, leading us to hope progress will continue
- It's an exciting field
- Prototype applications for quantum computers exist, on IBM QX and other quantum computers
Although it is a general concern that the field is overhyped, some experts are optimistic that the field in general is so close to being useful that the hype is warranted.
