With Moore’s Law slowing, engineers have been taking a cold hard look at what will keep computing going when it’s gone. Certainly artificial intelligence will play a role. So might quantum computing. But there are stranger things in the computing universe, and some of them got an airing at the IEEE International Conference on Rebooting Computing in November.
There were also some cool variations on classics such as reversible computing and neuromorphic chips. But some less-familiar ones got their time in the sun too, such as photonics chips that accelerate AI, nanomechanical comb-shaped logic, and a “hyperdimensional” speech recognition system. What follows includes a taste of both the strange and the potentially impactful.
