I can rely on some old, well-tested methods that are guaranteed to bring food on the table. At the same time, I can run another thread which explores an entirely new realm.

A person cannot do just _one_ thing, we have to switch tasks from time to time, in order to not get bored.

That’s why I don’t see why revolution and evolution should be mutually exclusive.

I must also say that revolution doesn’t have to be that expansive (in terms of how things get if you’re not lucky). Every revolution is a sum or evolutionary processes, isn’t it? All you need to do is take breaks every now and then, and evaluate your current status, see how things have changed since the last assessment, figure out what the risks are, think about ways to deal with them.

A revolution in technology can end in a disaster only if you haven’t done enough testing or planning.
