I'm 90% confident that the cinematic uncanny valley will be crossed in the next decade. The number applies to movies only, it doesn't apply to humanoid robots (1%) and video game characters (5%).
Edit: After posting this, I thought that my 90% estimate was underconfident, but then I remembered that we started the decade with Jar-Jar Binks and Gollum, and it took us almost ten years to reach the level of Emily and Jake Sully.
Not sure whether it's been fully crossed, but it's close.
By 2015 we had a CGI-on-top-of-body-double Paul Walker and audiences weren't sure when the clips of him were real ones. Rogue One had full-CGI Tarkin and Leia, though those were uncanny for some viewers (and successful for others). Can't think of another fully CGI human example.
(No, non-human humanoids still don't count, as impressive as Thanos was.)
I would like to propose this as a thread for people to write in their predictions for the next year and the next decade, when practical with probabilities attached. I'll probably make some in the comments.
