Dreams don't have deadlines. I'm thinking of doing bigger and better things and having more fun with it.
What I'm trying to say is the Holocaust was a horrific crime against humanity and frankly, I would never want to see that repeated.
It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
