How long do you think it will be before anime studios will change to doing only CGI

So I have been watching anime for almost a decade now and you can already see the changes that have happened over the years. It feels like we are getting close to an era where anime studios will stop doing hand painted animation and start only doing cgi like a lot of other countries have done. Its becoming super obvious in most modern shows of footage of 3d cgi than hand painted. I think it will be awhile before we get to an era like that but you can already see the changes.
