The version I described is the only one I've ever heard anyone else referring to.

Just because you can find someone referring to something else as a "technological singularity" doesn't mean it's reasonable to say that must, or even could, have been the definition the person I was replying to was using.

...And I think you'd be hard-pressed to find anyone to agree with you that "we founded companies" somehow satisfies the conditions of the Singularity, unless they're deeply invested in the idea that The Singularity Is Happening Now, and have entirely forgotten just what that's actually supposed to mean, or why they wanted it to be happening.
