The granddaddy of science fiction and futurism channels is Science Fiction and Futurism with Isaac Arthur. The channel has content for days about all kinds of shenanigans humans could be getting up to in space and beyond.
A close second is futurist and science fiction author John Michael Godier. His voice will either weigh your soul down to the core of the earth or you’ll find it grating… there’s really no in-between.
*especially if you’ve got nothing to hide.
