Not uninsurable, but buildings are going to have to become tougher.

It's happened before. Chicago's reaction to the Great Fire was simple - no more building wooden houses. Chicago went all brick. Still is, mostly.

The trouble is, brick isn't earthquake resistant. Not without steel reinforcement.

I live in a house built of cinder block filled with concrete reinforced with steel. A commercial builder built this as his personal residence in 1950. The walls look like a commercial building. The outside is just painted cinder block. Works fine, survived the 1989 earthquake without damage, low maintenance. It's not what most people want today in the US.

Note that brick is much worse than wood for wind-stoked wildfires; think ‘explosive fiery-hot shrapnel’ rather than just catching on fire like wood.

(This is not a contradiction of your point, just a useful related factoid for the modern era.)

You're going to die if you're around to witness either (if you didn't already pass out from smoke/heat/lack of oxygen). It literally doesn't matter.

The advantage of suburbs in which houses are mostly built from non-flammable materials is that while maybe one or two rows of houses closest to forested areas will likely burn out, there won't be enough calorific potential for the fire to propagate further into the suburb.

Also for firefighting efforts the difference between a house burning out and a house burning down is huge. The former means that most of the fire is already contained in a non-flammable structure, reducing the risk of spreading and also making efforts to quench it with water more effective.

"Brick is much worse than wood for wind-stoked wildfires" is a strange take. If a wildfire is approaching, I'll take a town built from brick rather than plywood any day.

Brick does tend to survive. Brick as an insulating layer can save lives. Brick also explodes violently under conditions where wood merely burns. Neither of these save homes in our wildfires, though; it turns out what saves homes is things no one realized at first:

Don’t plant trees within fifty feet of a structure. More, if you didn’t inflate your home like a balloon to fill a property to the brim with home. Cut them down and make a firebreak. Clearings exist for a real and serious reason. Aesthetics have been given precedence far too long in this regard.

Make your home airtight (or positively pressurize it, if you have the power and tech to do that safely) so that embers don’t get pushed in by the winds and pulled in by the temperature differential currents and catch your house on fire from inside its walls. Not much fun in having a brick building burned out from embers that were forced in through a poorly-sealed door.

Saturate your roof with water, so that it doesn’t trap embers and act as a fire repeater to the next house on the block. Not only will your roof not burn, but every ember that lands on it will likely go out. Even if your roof is metal, consider installing sprinklers anyways. Maybe you’ll help save your neighborhood someday.

It’s not the building material that’s the one problem here; it’s the carelessness of building code, safety enforcement and absence of federal and state aid to fireproof homes in known fire zones. It’s the catastrophically incorrect hundred year old policy that would rather burn down a chunk of homes every ten years rather than admit that policy is wrong and that the indigenous people were right all along. Brick or wood or concrete or steel, none of these will stop the hottest fires with any certainty. We know what does, and we’ve allowed it to become unsafe to have wood homes. We know how to stop these wildfires. Build with brick if you like, but:

Only fire can prevent forest fires.
