I think the "geek vs non-geek" thing is the root here.

What makes a geek? Is it knowing how to program? If you take your average sales guy and teach them js, do they suddenly become a "geek"?

If by "geek" we mean "bad at sales," then yeah, no shit they have weaknesses, it's tautological. If we mean "is technically competent," would making a non-competent person competent suddenly make them a "geek" and now subject to a bunch of new weaknesses?

Actually, as measured, I think it would, just like someone could no longer eat mystery meat with the same gusto if they knew what went into it.
