So I haven't watched this video. But in the age of deepfakes, with a click bait title, why should I believe video anymore? Especially "rare, lost" ones? And presumably ones with a point to push? What do HNers do to assess the provenance / authenticity of video in 2026 and beyond?

Can't confirm if it's real or fake, but I skipped around and it's just the same "predictions" he's been making for a few decades. He's going to build the biggest bestest rockets, we'll live on Mars, he'll make the fastest car and it will also be able to fly, etc.

His disgusting father never patted him on the head and told him he's a good boy for reading Popular Mechanics and sci fi novels, and now we all have to live through this.
