I'm 37, I'm starting to get worried about my age being a problem. But to hell with blaming employers who don't want me, it's their call. I think that maybe the actual problem is that by 40 they expect that I should be leading teams not just stuck at senior dev. Personally I want out of tech as I see supply and demand acting on wages (I'm in UK). Pretty soon, as far as I can estimate, it will go the way manufacturing went in the west: gone or heavily unionised blue collar like Germany which I don't want to be.
