Fusion isn't a good example. It's not getting anywhere near the funding it requires. Maybe I've become cynical, but it seems like all the big new technology products which have come out in the last decade or two have just been software products mostly designed to predict human behavior more accurately to advertise to us.

It's hard to imagine we'll hold Google, Apple, or Facebook in the same reverence 100 years from now because they created some interesting consumer products which distract us for a couple years before going in the trash to be replaced by the next, slightly more distracting version
