"A shameless recycling of existing content to drive additional audience engagement on the cheap… or the single best, most valuable, and most insight-dense episode we put out in the entire year, depending on how you want to look at it." — Rob Wiblin

It’s that magical time of year once again — highlightapalooza! Stick around for one top bit from each episode, including:

• How to use the microphone on someone’s mobile phone to figure out what password they’re typing into their laptop
• Why mercilessly driving the New World screwworm to extinction could be the most compassionate thing humanity has ever done
• Why evolutionary psychology doesn’t support a cynical view of human nature but actually explains why so many of us are intensely sensitive to the harms we cause to others
• How superforecasters and domain experts seem to disagree so much about AI risk, but when you zoom in it’s mostly a disagreement about timing
• Why the sceptics are wrong and you will want to use robot nannies to take care of your kids — and also why despite having big worries about the development of AGI, Carl Shulman is strongly against efforts to pause AI research today
• How much of the gender pay gap is due to direct pay discrimination vs other factors
• How cleaner wrasse fish blow the mirror test out of the water
• Why effective altruism may be too big a tent to work well
• How we could best motivate pharma companies to test existing drugs to see if they help cure other diseases — something they currently have no reason to bother with

…as well as 27 other top observations and arguments from the past year of the show.

Check out the full transcript and episode links on the 80,000 Hours website.

Remember that all of these clips come from the 20-minute highlight reels we make for every episode, which are released on our sister feed, 80k After Hours. So if you’re struggling to keep up with our regularly scheduled entertainment, you can still get the best parts of our conversations there.

It has been a hell of a year, and we can only imagine next year is going to be even weirder — but Luisa and Rob will be here to keep you company as Earth hurtles through the galaxy to a fate as yet unknown.

Enjoy, and look forward to speaking with you in 2025!
