I believe the current system is already over saturated and the online players Amazon, Apple, Google, Netflix, Tencent, Alibaba, Facebook and Microsoft are already encroaching on each others territories. Also a lot of the companies already posses powerful network effects and product synergies that make the entry of newcomers almost impossible. I'm force to remember every time I see a new VC investment that the purpose of VC is not to make the next tech giant like a Microsoft but to rapidly make a exit. I'm really sad by the current investment in tech but perhaps the real investments in disease treatment/space exploration are being ignored by the mass media.
