I've invested a (very) small amount in QRL but it's not really about ROI, it's more that I think it's important to start researching these things.
You can do whatever you want but I do not think we are even close to create a quantum computer capable of breaking the current algorithms, while some people speculate that we may be far more advanced I think it is going to take a lot of time, similar to what happens to robots.
I agree but there is a lot of money being put towards researching technologies that are decades away and very little money going towards more niche applications of it. Sure there's a lot of money going into quantum computing and there's a lot of money going into crypto currency so I think we can be fairly confident in doing that they will both be part of our future. What there isn't much money in is how well these technologies will interact with each other and what the dangers are. I'm not quite the zealot that OP seems to be but I would resent a little bit of money being lost to QRL of it means that another company in the future has done ects information to work with.
And who knows, there might be a 1000% ROI in 5 years
