Potential mistakes/clarifications: "and the random-seed speedrun record is under seven minutes" that's a 1.16.1 time. 1.16.2+ speedrun fastest time is 13-14 min, Gemini used 1.20.4, so that's a more relevant comparison. "collecting blaze rods and ender pearls in the Nether" - you can collect ender pearls in the overworld too, for example as drops from Endermen, trading with villagers, or from chests in the stronghold. "and an ender pearl, dropped by Endermen" - can also be obtained by trading with piglins in the nether or villagers in the overworld, both valid strategies used by speedrunners. "... requires ... destroying the ten crystals that heal the dragon in the End" - you don't need to destroy the crystals, speedrunners generally don't do that, just wait for a perch and kill it with bed explosions, pretty easy tbh (36:22 here: youtu.be/c2Y6duJD_jI?t=2182) "The estimate was 43m from the actual portal room." - ender eye in 1.20.4 points towards the corner of the 16x16 chunk with the entrance staircase of the stronghold (that leads nowhere if you go up). So Gemini probably estimated this coordinate very precisely, but then had to find the portal room from that starting position. Iron tools are not required, speedrunners get iron pickaxes to be able to mine gold blocks in bastions for trading. Unless you count the iron bucket as a tool. "DreamerV3 collected diamonds from scratch with reinforcement learning" - not in Minecraft, but in an extremely simplified version of Minecraft, easier even than Crafter. Crafter is a 2D toy version of Minecraft created by the same author... (tweet) "requires ... using math to locate a hidden underground fortress" - it does not require math or even rough triangulation, you can just follow the ender eye where it leads you and you'll reach the stronghold.
