Okay, a couple of questions here:
1. Is Apple the top three most important company even right now? Don't mistaken me, I love Apple.
2. Like many doubters here, I wonder if Facebook can even be relevant in 2020. Google succeed because it does not limit itself to its original service (searching) and created tons of other cool services that a lot of people want. The question is whether Facebook can pull that off? Not yet at least.
3. If there is some company beating Google I am thinking of a company in AI with some tech breakthrough. But then the question is, would Google have enough smart people to "copy" it and make it better? I am somewhat awed at what Google can achieve at this moment. Next Google please comes up.
