I hope Bluesky is able to find a model that works for them AND for consumers. (I do know it's an open protocol, so it'll live on without Bluesky itself! However, as this post shows, it's a lot of work to build on the prototype... so if not them, who? And if someone else, how will they become sustainable?)
Like, sure, they don't need every single one of those 30,000... but they have to have ground teams in every city in the world. Connections with every airport. Connections with almost every restaurant in the world. Customer support and safety (okay I know they don't nail this, but still). They need to pay out drivers in each country. The app needs to work in hundreds of countries, all with different laws, currencies, languages and more. Some places let you pick up anywhere, others require specific locations. And that's not even including marketing, partnerships, HR, finance, etc.
I don't think the employees are the problem with Uber, it's the shareholders. They need to make X back, so that delta is where drivers get squeezed.
