The concept of nondeterminism in computation is one of the most important ideas in computer science.

Money is overrated. Truly new things rarely need an abundance of money. If that was so， billionaires would have a monopoly on inventing new things， and they don’t. Instead almost all breakthroughs are made by those who lack money， because they are forced to rely on their passion， persistence and ingenuity to figure out new ways. Being poor is an advantage in innovation.
