He gives his reasons as a Nobel winning physicist, who ranks up there with Einstein, why he thinks we never been and never will be visited by alien beings from outer space. This has changed my opinion on UFOs substantially.

1. Einstein? Very doubtful;
2. Carl Sagan would have disagreed vehemently;
3. Richard Feynman is dead (1918–1988). There was no such thing as the internet or YT in 1988 BTW. You are watching AI generated content of dubious value.
Carl Sagan acknowledged the questions raised by the Fermi paradox and the issues of time, distance, the speed limit of light, energy (the rocket equation) and biological constraints. He didn’t come to the exact bleak conclusions as Feynman but he acknowledged the seriousness of the issues.
Carl Sagan is a fraud. His nuclear winter theory is junk and was spectacularly disproven by the first gulf war when he falsely predicted an environmental apocalypse (that never came) caused by oil fields burning. Bringing him to the same league as Feynman is out of touch.
And it was said those “Feynman videos” were AI generated. The AI part is the voiceover, but the content is from Feynman lectures, nothing of “dubious value”. On the contrary, it’s quite good pedagogy.
