Uber the company may be in trouble, but Uber the brand will be driving people around for decades to come.
I still wouldn't buy them right now, though.
I reported a bug in their app in a review I left on the Play Store. Uber responded saying to report it on their website instead. I did so, they told me it wasn't valid because I didn't include screenshots. (Even though there was a clear description of repro and expected/observed behaviour). After a few days I got around to sending them screenshots, and received an auto-reply that the issue had been closed and my reply rejected.
However, people can mistake a frat bro culture with actually high productivity (leaving aside questions of whether employees are harmed by the culture). Zenefits pre-Parkers-leave might be an example. Employees can't be getting drunk and having sex in stairwells during office hours and retain a high level of productivity.
From my perspective, that would be prima facie wrong. I've witnessed frat bro cultures that led to that and ones that haven't. Just like every other type of culture.
Maybe we aren't talking about the same thing.
What I have in mind is a culture where personal boundaries are a bit relaxed, people are abnormally loud when communicating, etc. There is a sort of shallow resemblance to general sports culture.
Remember that Steve Jobs helped Apple by killing a lot of products and simplifying their offerings. In the latest numbers release, rides were "profitable"; Uber Eats wasn't. I would agree that if Uber focused on the core product, and eliminated all the side projects, in the long run it would work best.
There are other apps comings, and there is regulation coming as well.
Not where I live. Where I live, taxis are beating the pants off of Uber and Lyft. This certainly isn't true everywhere, but it does show that taxis absolutely can compete with Uber and Lyft if they have their acts together.
