Yeah it's not leaving the pop culture consciousness anytime soon. For one, it's a think piece machine. People love to write about it, make videos about it, dissect it's themes, and that goes for people that love and hate it. It gets people talking. Even academics, so it'll stay relevant via classrooms where it'll be talked about in film and social studies classes.
Then there are the memes, quotes, and language it has introduced into the lexicon. Sunken place, where the keys, tea cup sounds, that shyt is here to stay for awhile. Especially the sunken place reference.
And though it's too early to measure it, you have to think it's success will influence future projects. We already have a
Tales from the Hood sequel in pre-production, and Jordan was already given a new film he gets to write and direct for Universal set to release in 2019, and a HBO series, all based on the success of Get Out (that $250 million return got the studios like
). If this leads to several more successful projects from Jordan, Daniel, black horror films, etc then people will forever remember what kicked it off.
Get Out is a cultural marker in time that people will point back to 10, 20 years from now. Can't say the same for, Three Billboards, or Phantom Thread, or Darkest Hour. And that says nothing about the quality of those films.
