The use of AI generated slop for a podcast that evidently has the financial backing to pay artists is both insulting and genuinely just really cheap.
Do better. This stinks
I enjoy this show. There’s always something I learn when I listen to it.
This podcast is a fun way to explore alternate realities using scientific reasoning. I love how it opens the mind to new and intriguing scenarios. I can’t wait to listen to all the episodes! Great podcast! Thanks for putting this together!
…when Philip Shane and Prof. Matt Stanley delve into one of their scientific / technological / cultural ”what the ifs”. The best that I know the responses from Matt Stanley are mainly improvised on the spot (which gave me a weird tangent, as the voice of Matt sounds very similar to the know-it-all droid C-53 from Mission-to-Zyxx, an equally improvised, albeit fully fictional, great podcast)
Super fun!
