You don't think tech leaders have changed at all, in any way?

Many of the most prominent American tech leaders these days are of Indian origin. The social stigma to tech is not present in Indian culture, which stems from India having been under British colonial rule and the accompanying de-industrialisation of India. https://en.wikipedia.org/wiki/De-industrialisation_of_India

I don't there's any reasonable way to have a conversation about trends when you're only talking about a dozen famous people.

Yes Elon lost his marbles but my colleagues have not suddenly become "tech bro" that we constantly hear about today.
