I’ve done some blacksmithing as a hobby. The two most common ways of heating the metal are a gas or a coal forge. The coal forge normally has some sort of forced air coming from the bottom to feed the fire. The coal starts burning real smoky like, but then turns to coke and burns hotter the more air you force through it. Typically you pile some coal around the sides of the fire so it converts to coke then you scoop it into the fire as needed. Also it produces a waste product called clinker that builds up at the bottom of the fire at the tuyere (the nozzle or grate the air is forced through). It’s kind of like stone or metal and it needs to be cleaned out to keep the fire going.

He’s referring to the fact that the Effective Altruism / Less Wrong crowd seems to be focused almost entirely on preventing an AI apocalypse at some point in the future, and they use a lot of obscure math and logic to explain why it’s much more important than dealing with war, homelessness, climate change, or any of the other issues that are causing actual humans to suffer today or are 100% certain to cause suffering in the near future.
