Yeah I understand all your points. But I'm saying that no company has been able to replicate the rapid rise and dominance of Facebook since the latter went public. Maybe in the next decade Uber or AirBnB or one of these SaaS players will have a major explosive new product or service, like Apple had with the iPod and later with the iPhone, and become a real tech behemoth. Time will tell.
