Nathalie Cabrol: Search for Alien Life | Lex Fridman Podcast #348
Lex Fridman
The contradiction between the high probability of extraterrestrial civilizations existing and the lack of observational evidence to support their existence.

Manolis Kellis: Meaning of Life, the Universe, and Everything | Lex Fridman Podcast #142
Lex Fridman
The question of why, if alien life is common in the universe, we haven't seen any evidence of it, potentially due to 'great filters'.
