We had Internet "everywhere" in 2000, all these new doors were being opened! And yet we crashed. The investment has to remain in step with the economic returns, or else eventually a crash happens. The possibilities are one thing, the returns are something else. Of course there are a lot more viable online/mobile businesses now than there were in 2000, so a bubble has that much more space to grow before crashing. If there's a bubble.
