That has already been an enormous revolution in space access, and it's just the beginning. They haven't been landing rockets for shits and giggles. Relative to the cost of a rocket, fuel is practically free. The real cost is in the actual materials for the rocket and engines. And previously companies have just thrown those away. Even the Space Shuttle had 'reuse' only on paper rather than any significant reusability. But the Falcon rockets are genuinely reusable, and them autonomously landing rockets is now, amazingly, starting to become business as usual. Go for a flight proven rocket and the costs drop even further.
This is only what has already happened. None of this is future or speculative. This is happening at this very moment. If you want to see what the plants are then look into the goals for the BFR and Mars. This is the thing that's so disappointing. We're currently going through one of the biggest revolutions in technology today, that will likely be a keystone moment for our species' entire existence, and most people have absolutely no idea the relevance or scale of what's happening - instead distracted by irrelevancies that nobody will even remember in 10 years, and in many cases - 10 months if not 10 weeks.
