Maybe working on web stuff is still too culture dependent or even just young space to have enough of old people as changing industries is always hard when you are well in your career.

Skill set is key. What you don't want to be is the old guy with the same skill set as people who are expecting to make half what you expect to make.

My age, coupled with with the fact that I prefer machines over people doesn't endear me to this newer generation of techs. I have been asked at my last several jobs why I don't use Facebook, LinkedIn, or any other social media.

I'm a greybeard and I like it that way. I'll gladly ride out the terminal windows job and light programming until they show me the door. Meetings and budgets are for others...

You are isolating yourself as well though. One study I read is that biases appear in full force after two stereotypes are validated.

Just like those kernel hackers mentioned above, or the people writing business operation code in Cobol on a main-frame.

With stock grants? Maybe that's taxable. But uh, wow. It's not "well beyond 6 figures."

As an aside, my optometrist told me that the company with the best vision coverage that she was aware of was not any of the big four, but Oracle.
