I'm having a hard time pulling the trigger on a new big ring, so before I do, I thought I'd ask about your mileage before you guys replace them.
FWIW, we're talking about a Force 22 50 tooth ring.

I have 15,000 miles on a Red 22 50T and not signs of wear.

Yeah, that's what I was thinking. I have more miles than I can remember on a vintage Sugino, but when my Sram Force chain wore out at 3k, I started getting a bit worried about my big ring.
The tips of the teeth show some minor wear, but the valleys look good.
That's a hundred bucks I can spend on something else now.

That sounds a little short for cassette wear, but if most of the riding is flatland, a few cogs could wear out faster than if the terrain is more varied.
25-30k miles is about normal, if you spend most of the time in the big ring.

The ring on my oldest bike has over 50k miles on it, with very little attention ever given to things like chain wear.
The teeth are worn to roughly half their original thickness, but i never had any issues.
IMO, something is seriously wrong if you're not getting at least 20,000 road miles on a ring.

I generally count on 20,000 miles. Even then, they usually function pretty well, but the valleys begin to wear into the structure of the ring. At that point, why tempt fate? Chainrings are (relatively) cheap.

Maybe your faith has gone away and the cycling gods are punishing you. Maybe you need some churching up.

Of course all of these responses do not take into account your shifting habits, or the power you put out. Personally I just changed both rings on my SRAM Red Cranks this year. They were from 2012 but I took a year and a half off in the middle. No way I have 10k on them. While mine looked ok I was having shifting issues at one point and I think I damaged a few teeth so I decided to change everything and make sure it was all good. Got new FD, new rings, new chain and new cassette...shifts like a dream again and no dropping. Force and Red use the same rings FWIW.

Here's the solution for those of you who wear your aluminum (or is it aluminium? 
) chainrings down early.
Surly stainless steel chainrings available for a variety of BCDs and tooth numbers.

I believe WolfeTooth Components also makes some.

I ride 6000 miles a year or so. I do have multiple bike so not all on one bike. But in my lifetime, I've never replaced a road bike chain ring due to wear.

I just replaced my 2010 Force 50 tooth at 15,000 or so. Was getting some mis-shifts and a couple teeth looked damaged. Seemed to correct the problem. Not sure where the damage came from.

Even if you have only one bike, 30-50k is 10 years of riding even for a reasonably avid cyclist.

10 years and at least 30,000 on an ultegra and no noticeable issues.
