The issue I have with what you and mkramlich say is that you're jumping from an observation to a conclusion about causality. I'm just asking, what is the basis for your assumptions about causality?

You say that people took it too far in the past. Why was that? I think that they didn't just take it too far, they made a categorical and methodical mistake. They did not question the basis on which to make such assumptions. In that sense, you're making the same mistake today.

[Edit] And don't forget that we're talking about something - web startups and entrepreneurship - that takes an incredibly broad range of capabilities that have nothing to do with having babies. It's not like we're talking about interest and talent for breast feeding. And by the way, I totally agree with Arrington. He doesn't say anything about why we see what we see though.
