I think the argument is that if everyone in SF is tech focused now, despite different backgrounds, there is a lack of diversity in the interests of the groups taking over SF (techies), where there used to be diversity. So now, everyone's a techie, instead of maybe musicians or artists, etc. I'm not sure it's a good argument, but I think I agreed with it briefly.
