I work with ideas about computers. I think about the things computers can do, and I try to find ways to make computers do those things better or faster, and I write all those ideas down. And I try to find ways to stop computers from ever being slow, so that we don’t have to make them faster. I also think a lot about if there are things that computers can or can’t do, and if it’s important that computers can or can’t do them. It’s bad for people when computers are slow or when computers can’t do things because we want computers to help us with things we want to do. But making computers do things that they can’t do is hard, and making computers go faster can be hard too. So sometimes I use ideas from other people to make the things computers do faster or better, and sometimes I find my own ideas too, and then I write those ideas down and tell everyone about them so all of us can make computers do more things better.
