OK, I'll try: a character from an ancient tragedy with hubris would now be psychologized as "narcissistic." Or something.
Or even just called "very self-confident" as though that's a good thing.
Suppose our "tragic hero" is a Director of Engineering or Marketing, and they decide to become an entrepreneur. They fail spectacularly. A modern audience wouldn't say they were a victim of hubris. Maybe they really were.
On the other hand: Walter White could be one, as Gioia suggests. But Vince Gilligan has actually said that Ikiru was his inspiration (a character who "broke good"), rather than any classical tragedy.
So I don't think it's really that we're in a "digital age," it's just that we have a lot more explanations for things than the classicists did.
