"Build something in your garage" could be tech related. But it's important to do things other than work.

The image of the tech titan that got started in their garage was the standard thing not that long ago. I actually can't remember the last time I saw it. Now it seems like it's "get in the ground floor on someone else's world-changing startup."

Is this just my limited perspective or has the narrative really shifted?

I don't see anything I said that is demeaning. I didn't say it was a shitty thing to not have a life outside tech.

If you never get burned out or otherwise disillusioned with "tech", more power to you.

I suspect most of us eventually find we need something more in our lives though — I was addressing those people (and I suspect the article was as well).
