These are terrible examples because they are not reality. In a rational world they would not have been able to go public with the numbers and lack of rational plan to solve it they have. You do not have to be profitable but you have to because to explain away to get there that makes sense. For Uber and Lyft, I do not think they can. Time will tell. WeWork is a example of rationality returning after Uber, Lyft. I would suggest for tech VMware, Arista, RedHat are far more rational guides.
