I didn’t yet find a good answer to how miners will be able to keep their revenue stable or even increase it. Fees are low and mining reward gets cut in half every four years..
At this point we are doing a lot of speculation

That’s entirely different question.
I think in a few years mining as it is now will basically go extinct. My expectation is more usecases like heating water/air for reuse purposes, burning flare gas and/or mining as a precursor to building other infrastructure will inevitably emerge.
