Solar and wind, with battery storage, can get you to say 90%, and then you only need 10% from other sources like geothermal and nuclear to fully decarbonize.

Solar is at 7%. It's very significant.

That’s my point. Solar is on track to eclipse that amount way before we would build all of this speculative geothermal.

Just make everything part of the mix, even dam to dam hydro on rural hillsides plays a part in stabilising grid edges.

The more interesting use of geothermal power, IMO, is pushing heat underground with excess solar while the sun is high and the days are long, and pulling out electricity from heat in the darker times .. done large enough that carries across summer to winter.
