Desalination must be insanely expensive; I’m always shocked it wasn’t done decades ago.
Considering California always seems to have power and water issues, I’d think combining these things would make a lot of sense. Some of these exist and there seems to be a fair bit of research in the area. I have to image at some point that will be the direction California would need to go. Of course, if they are all-in on solar and wind, then maybe not.

It isn't. Mostly there are environmental concerns.
Prove it.
Show us the data.
What is the price of desalinated water vs water that literally falls from the sky.
They both need to be chlorinated and piped to the end user, but desalinated water is typically at the wrong end of existing delivery infrastructure to take advantage of it.
And irrigators often have things like God deliver much of their water via rain, rivers etc.
So it stands to reason that desalinated water must be much more expensive.
Did reverse osmosis suddenly become energetically inexpensive while I wasn’t paying attention?
Did we build a bunch of nuclear power plants by the coast to use the waste heat for flash distillation?
Did brine disposal suddenly become a trivial issue to solve?
