A lot of folks are look forward to what's coming in tech, which is fine and good and can lead to promising careers and innovation. But I'm even more impressed with folks like Nintendo who do the exact opposite. They look at all the junk we've already passed up to see what can be done with it. So many times along their path they came up with products using what the Sony's would have considered obsolete junk. This is a great book about that history: https://www.amazon.com/Super-Mario-Nintendo-Conquered-Americ...

I mention it because I think there's a lot of value looking at the "no longer promising" areas and see what can still be done with those tools and pieces in innovative ways. And so few are actually doing that.
