I'd love to hear this. It's not something I've noticed in my plentiful YouTube watching, etc, but I think it'd be an interesting development. The English-inspired "posh" American accents of yesteryear are beautiful, I think.
The similar thing that stands out to me like a sore thumb (and I appreciate this is all on me and anyone can talk however they like!) is when British people keep their accent but drop their "t"s to "d"s when speaking in public/on YouTube/podcasts/etc. ("Bedder" instead of "better", for example.) It doesn't seem to be a youth only thing, a lot of British speakers at tech conferences seem to do it, but it's not how we'd talk amongst ourselves in the UK. I wonder if it's something to do with subconsciously reducing plosives which often come out bad on mic?
