Are movie theaters dead, or is the big screen irreplaceable?

My nephew is seventeen and has seen exactly two movies in a theater in his life, both on school field trips. He watched Oppenheimer on his phone, in two sittings, while texting through the quiet parts, and he considers that a complete and normal viewing experience. His friends are the same, and the surveys back it up: younger viewers increasingly prefer watching on phones and treat the big screen as an occasional novelty (Deloitte). There's a whole generation forming its relationship to film without any nostalgia for the marquee, the sticky floors, any of it, and nostalgia was the only thing keeping the lights on. You can't kill what was never alive for them. Theaters aren't being replaced by home theaters so much as by the phone, and the phone already won.
