In fact, I’d go further and say it’s explicitly a good thing. While there are some advantages to concentration of industries, it’s unhealthy when taken to an extreme.

> It’s why Austin/Portland/etc grow in these areas.

Realize you're being colloquial here, but I think it's a bit SF centric to credit SF with growth occurring in other areas of the country... In the case of ATX you have at least UTexas & Michael Dell not playing a small part in the tech growth there, for starters..

If you look at the migration patterns of people in NorCal it’s really not. Hell, just ask the locals - it’s a damn cliche in Austin or Portland that ppl moved in from NorCal to there.

Also if you look at the businesses, networking, and where the VC money comes from, the SV connection is clear.

Flight from the Bay Area has absolutely powered a lot of growth in those places.

They were cool places in the first place of course, but that is why they were attractive to move to.

Agreed. We'll never solve diversity in tech if all the jobs are concentrated in the Bay Area.

Didn't Portland (well, Hillsboro) have 5 huge Intel campuses, with all the tech talent that comes along with those, for a lot longer than Silicon Valley has been a thing?

Portland has had two waves of growth - the first was due to Seattle’s tech scene.

So yes they did - due to that one.
