Like they say fools are always so sure! But its really hard to say how things turn out. I remember reading back in school how Amazon was so over prized and how it was doomed to fail (during late 90s). We all know how it turned out.<p>It could just be survivor bias. But the thing is - its hard to predict the future and to be certain of any prediction is profoundly inane.<p>PS: NOM to author. I really like David and I used to have the same opinion of FB at that time.
