I really like his answer to a question about Academy's setting:

So you’re setting this —

In the “Discovery” era. There’s a specific reason for that. As the father of a 17-year-old boy, I see what my son is feeling as he looks at the world and to his future. I see the uncertainty; I see all the things we took for granted as given are not certainties for him. I see him recognizing he’s inheriting an enormous mess to clean up and it’s going to be on his generation to figure out how to do that, and that’s a lot to ask of a kid. My thinking was, if we set “Starfleet Academy” in the halcyon days of the Federation where everything was fine, it’s not going to speak to what kids are going through right now.

It’ll be a nice fantasy, but it’s not really going to be authentic. What’ll be authentic is to set it in the timeline where this is the first class back after over 100 years, and they are coming into a world that is only beginning to recover from a cataclysm — which was the Burn, as established on “Star Trek: Discovery,” where the Federation was greatly diminished. So they’re the first who’ll inherit, who’ll re-inherit, the task of exploration as a primary goal, because there just wasn’t room for that during the Burn — everybody was playing defense. It’s an incredibly optimistic show, an incredibly fun show; it’s a very funny show, and it’s a very emotional show. I think these kids, in different ways, are going to represent what a lot of kids are feeling now.
