I'm uncertain if this is true. The market is the market is the market. The value of a company is what investors believe it to be. In tech, unlike an industry like lets say, Automobiles, this "worth" is very difficult to quantify. Tech companies can be scaled to near infinity (Apple) or go to zero with one wrong move. Investors are placing their bets.

Whatever industry replaces "tech" as the next great revolution (perhaps AI?) will have "bubbles" orders of magnitudes greater than what we're seeing now. If you think we're in a bubble now, which we very well could be (I'm unsure), just wait for the future.
