If anything though, this shows that at least tech driven hype bubbles can stay around way longer than we think if we are looking at it from a product POV.
This just means short sellers might have a hard time sinking a hype-category stock with reasoned research because the irrationality keeps it afloat.
"Markets can remain irrational longer than you can remain solvent." - John Maynard Keynes
Sometimes I wonder if Keynes would under the current conditions see fit to differentiate "merely irrational" from "absolutely insane".
