Thank you very much for the question.
I think there are a couple of things. The history of innovation is probably helpful to look at here. They said exactly the same thing about fracking for 50 years, that it would never work and never be profitable. One determined entrepreneur spent tens of millions of his own dollars and proved that it could.
There are numerous examples of technologies. Now, innovation is a messy business. Innovation is a slow business, until it's not. I would reference Matt Ridley's work on this. It's messy and slow until we hit something, and then it takes off. We just don't know when that's going to be.
