Anyone who's a good enough bullshit artist to fool you while talking tech for an hour should be in a totally different field, because such extremely high levels of bullshitting ability are themselves quite lucrative.

I just can't believe there are so many people out there with the skill and will to do that, who also haven't found a better way to employ those skills directly, that our field can be awash in them. I believe there are plenty who try, but I doubt there are very many who could talk about tech and their career for an hour without tipping their hand.
