From my email:
We are now starting to get a hint of the future transformative technologies that you guessed were on their way in “The Great Stagnation”. You had not speculated on what they might be, but there are faint hints on what is likely to happen.I believe this article is one leg: extremely fast air travel. The second leg is the Hyperloop and similar: extremely fast ground travel. The third leg is synthetic biology (e.g: https://www.economist.com/leaders/2019/04/04/the-promise-and-perils-of-synthetic-biology). The fourth leg is quantum computing, which is finally starting to show that it might work. And the fifth, and final leg, is fusion energy, which looks eerily like it will actually come to fruition this time.Put those 5 together and you have the makings of a new economy, with a huge burst of growth to come for many decades. These are just faint hints, of course, but they’re starting to get increasingly clear.
