I mean reliably, the same way a human does. I can make a lasagne tonight, or lobster risotto, or whatever. I can decide on a thing, buy ingredients, chop things, get that lobster out of the shells, find the right recipe, substitute according to taste, and loads of other things that are somewhat related to making food. I can wash the pan I need, improvise a stove lighter if the igniter fails, etc.

We might be able to make machines to do each of those tasks, but that's not the answer. I might do 100,000 things in an average week. Clearly we aren't going to build 100,000 bespoke CNNs and LSTMs. To worry about superhuman AI, we probably have to figure out how to make one or a few machines that aren't gloried deep fryers.
