I currently have a Youtube phase and like:

• Charlatan Wonder and Charl(his cat) for Immersive Sims
• Redlyne for the more obscure entries in gaming and adjacent areas (i loved his exploration of dead online spaces)
• oboeshoesgames for funny, more indepth stuff, oboeshoestwos for "bottom of the barrel" steam games and some surprisingly good games that do not have anyone playing them
• Denys Davydov well sourced daily Ukraine updates
• INSIDE RUSSIA for how the SMO changes Russia and how the russian system works
• Perun for everything military
• The rest is Science with the Vsauce guy and Hannah Fry, Hannah Fry herself too
• Louis Rossman, Gamers Nexus and GNCA for Hardware and consumer rights
• Technology Connections, Veratisium, CPG Gray, 3brown1blue, NileRed, Styropyro, Codys Lab, Elektroboom and Chem Thug for more Sciencey Stuff, Chubbyemu for medical stuff
• Strange Aeons and Lessons in Meme Culture for Subcultures and to be up to date on popular Memes
• Legal Eagle for US legal stuff and Reckless Ben because he's insane in a good way

Edit: a few of them are currently inactive, like CPG Gray (but the Cortex Podcast is still going), but there's so much great stuff there that you won't run out for a while
