I particularly love this last sentence of yours as I believe it summarizes the situation perfectly: Medium by itself doesn’t offer a future for any writer.
The thing is — we should’ve all known this way before we invested so much into this platform.

The problem is just:
When you don’t make money from it, then you can’t justify spending hours every single day doing it.
