You think people havent got it wrong before...look at dot com look at biotech...look at the phone boom...look at gold in the 80s and 90s...look at financial stocks now...or property trusts.
They all boomed and busted whilst being called new paradigms and once in a lifetime...job lay offs and drop in pay occured every time.
Same old story
If you beleive the hype in a bull market then good luck to you...
