The fact that people are generally uncritical of this growth claim is just stunning. You have to believe that this is as big as smartphones while ignoring all of the differences with this cycle of hype.
Nobody intelligent is actually uncritical about these growth claims. What you are seeing is the other side of "the market can remain irrational longer than you can remain liquid". There's no financial benefit to calling bullshit, because timing when the market is suddenly going to correct is impossible. Rational investors are either in the market of boosting the stock to sell it in the short term (a bigger fools scam) or staying as far away from it as possible.
It doesn't have to hit the projections. It just has to keep looking like it could 2 months from now when you sell.
The market has never been determined by the actual value of the underlying tangible thing, but rather the market value of that tangible thing. Although they may seem similar they are not the same. As the market becomes increasingly detached from reality, you'll see more of this.
