      So fast path finding can be done by pairing "2 hop hub labelling" and A* - scales linearly in mem, sub ms query times

      Only downside is that you need about a TeraByte of RAM to build the index - hahahaha; "we should just buy this computer" - lol Mikola

      Apparently that's how Microsoft got the 2HHL algorithm to run - 1 terabyte of RAM

      Mikola is now explaining how the 2HHL algorithm works, and why it needs so much RAM. He's taking us all to computer school 🚓

      2HHL works for our roads systems, but not arbitrary graphs - it works because in practice our roads are built around hubs. Think highways
