Stockpile, yes, but I don't think going for a secondary skill is necessary. It's not like people in tech are going to suddenly not be able to find work in tech, it'll just be less lucrative. I'm willing to bet it'll still be more than most people in other industries will make.

Edit: I mean, I guess there's always the post-apocalyptic scenario, which isn't out of the realm of possibility. If that happens it may be helpful to have secondary skills in making football pad armor or knowing how to make fuel from pig shit. But, as long as civilization still stands, I don't think tech people need to start hedging their bets by skilling up as an accountant or something.

Not a bad idea. Wish I had stockpiled more before all this crazy inflation hit.
