I've probably derailed the thread too much so will give a cliff notes version and then let the topic get back to the price and trading of MAID.
Perez feels technological revolutions drive growth and tend to follow the same pattern, which lasts roughly 50 years: technological revolution --> financial bubble --> crash --> golden age --> political unrest.
She also identifies 5 of these:
1) 1771 The Industrial Revolution Arkwright's cotton mill
2) 1829 Age of Steam and Railways Liverpool to Manchester Rocket steam train
3) 1875 Age of Steel The Carnegie Bessemer steel plant opens in Pittsburg
4) 1908 Age of Oil/Automobile/Mass Production Model T
5) 1971 Age of Information Intel microprocessor announced
The last technological revolution began 45 years ago, so if the model is correct and these happen approximately every 50 years we're due another one relatively soon. That seems to coincide with a whole raft of promising new technologies. The three main elements are usually communications (telegraph; telephone;internet), transport/logistics (train, car; autonomous car/drone) and energy (steam; oil and electricity; renewable energy) so if I had to guess I would say the next one will be driven by autonomous cars/drones and renewable energy.
