There's nothing wrong with suggesting that someone riding a road bike in pot-hole city is on the wrong bike. Even on a forum full of die-hard roadies.

But if the OP's happy with smashing a twiglet road bike over potholes at 25mph, and isn't open to alternatives, then there's little else to suggest.

No, 79pmooney used to live in the northeast. Several of us live in potholandia.

Suggest that rather than worrying about your fork, you learn when and how to get out of your saddle, and also learn how to repair flats.

And ignore the wrong bike crowd. And the wrong tire crowd. And the wrong....

I ride some pretty damn bumpy roads on my 25mm, urban and rural, and really there isn't that big a difference between them and my 36mm as long as I get off the saddle. For me, the handling on a street is much better with the 25s, so I'm able to avoid potholes with a lot less notice as well.

I had a plastic fork break in two once, but I was using it to hold a tough steak in place while trying to cut the steak with a plastic knife.

The people suggesting a fatter tire are offering good advice, because when you hit a pothole, the sequence of failure is: tube --> tire --> rim.

In other words, first you'll pinch flat. If it's worse than that, it might cut your tire or flat a tubeless tire. If it's worse than that, it might crack or dent your rim.

If it's worse than that, it might throw you over the bars after damaging your front wheel. But your fork will still probably be fine.

If you've ridden the route and are getting by with your current tires, there's no reason to worry about the rest. They're the canaries in the coal mine.

Carbon is extremely strong. Changing to a different material won't improve the durability of your fork.

Also, the notion that carbon parts snap without warning is mostly a myth. Like metal components, they fail progressively. If ever your steering starts feeling soft, stop riding. You likely have a damaged steering tube that may soon break off.
