Which is funny, because weren't we in tech the people who aspired to “think different”? But then it didn't become think-different for the individual but for the tech in-group against the "square", boring, formality-driven out-group. And since the world is becoming increasingly informal and any group worth its salt needs to differentiate itself, tech people might be the first to return to wearing suits and ties (or dresses) to work. I'd love that.
"Think different" was a marketing slogan used for Apple products from 1997 to 2002, back when Apple was aimed chiefly at video editing professionals. It was never aimed at techies.
As long as suits and ties remain the uniform of politicians and managers, I don't think techies will ever willingly adopt it for themselves as well.
