Not sure what is going on in QC world; With this ACM prize it has become even more murky.

I don't know enough about the science/technology to form an opinion but have recently started down the path of trying to understand it - https://news.ycombinator.com/item?id=46599807
Forever is a long time, but I agree people that assert reality is the model are almost always incorrect eventually.
