Time zones are how customers and businesses are synchronized, if they are not immediate neighbors. Time zones are a result of the invention of telegraphs and railways, for the first time making it necessary to know the local time of people you can't just walk over and ask. And as long as you don't abolish long distance communication and travel, the need for time zones will continue.

DST is for countries outside the Tropics, where the time of Sunrise and Dawn differs greatly between the saisons.
It makes sense for Brazil to have no DST. It makes sense for Minnesota to have it.
We don't have a problem with teens viewing porn in the UK. It just doesn't happen any more. In fact, we've been remarkably effective at stopping it compared to half the other countries in Europe, which have seen a recent surge in porn viewing for reasons no-one can identify.
Me too, though of course in our day, the world was much less connected and much less reliant on the technology. The worst we could have done after getting root access to the entire IT infrastructure at my school would have been look at what our classmates had been drawing in Paint or something. Today these systems host much more important and sensitive information and security breaches would be a much bigger deal.
And on that note, am I the only one less concerned by the behaviour of an impressively curious seven-year-old and more concerned by an official, professionally-managed system holding potentially sensitive data that is so insecure that even a seven-year-old could hack it?!
The experiments to put gas turbines into cars for sale ended two years before NOx mandates were enacted. They were continued for race cars, which aren't affected by the mandates, but fizzled out a few years later.
