Well it's pretty simple actually. World population is going up to 10 billion. No company can keep them all under 1 brand. It's just too many. Considering how intelligent 1 human can be. One thing is clear. Every time in history when we find something that is better then we never go back! Because we want to save time and energy that's how we are wired.
We are all working towards a better future. And it's working. But we are too zoomed in to see the bigger picture of what we are doing. Clearly we are living in some pretty wild times compared to for earlier people. But we have been super intelligent thousands of years ago.. The pyramids... Probably our AI can figure out how to build pyramids just like our ancestors did! ;)
