This week, Brian and Angelo take a look at being locked into certain technology ecosystems, and of course HomePod rings. Then, from HomePod rings, they take a look at the ring left by an incredible UFO sighting in Delphos, Kansas. Also, covered: phones that spy on you, ad blockers, photo backups (Brian’s favourite), time travellers, cryptocurrency vs SETI, and the Pentagon UFO tapes.
