Honestly this seems like an efficient use of waste-heat generated by the computer -- use it to keep you meal warm!
Maybe in the future recipes will come with cryptographic hashes you need to crack in order to warm your processors to the appropriate level and length for cooking
I started you mining Litecoin back in something like 2014, when I was in grad school. My appartment had purely resistive baseboard heating, so might as well mine some coin whole heating during Canadian winters right?
I stopped after making a few bucks because, well, I needed the PC to do my research work and investing in a dedicated rig wasn't really worth it (on a grad student budget).
