Film stars and pop stars etc of the future will be CGI.
The real stars of yesteryear and who are (as has been said) dying off at a rate of knots, will never be emulated in human form, ever again, in my opinion.
Pop stars are going to be similar.
Look at the holograms they can present on a stage to a live audience.
The holograms will be CGI characters belting out tunes.
The Oscars and Emmy awards and the likes, of the future, will be CGI film stars with given names just appearing to look like they're receiving awards in real life as we simply watch on TV or a major updated version of TV.
The weird thing about it all is, humans will idolise the CGI characters, because we are easily manipulated into anything.
I almost feel glad that I grew up in the 60's and that I'll likely expire in a decade or two, unless I'm seriously unlucky and live into my 80's.
Burt Reynolds and the likes were real grafting actors. As raw as the olden days but with extra TV colour mix.
