If it's true Elon's losing 4M USD a day, he might file for bankruptcy and the company will collapse within itself soon enough. Problem with twitter is that it couldn't monetize its users to the extent facebook can so he'll have to rely on Twitter blue revenue which is 8 USD/month. Entire company is dependent on whether Twitter blue can generate sufficient revenue. That is to say, twitter is doomed.
If Twitter were only dependent on Twitter blue revenue, it would be still unstable in the long term and of course it's doomed. What if Elon brings more revenue channels and makes the revenues continuous ? It seems like he is doing some experiment on Twitter and we'll have to wait for the final result.
