The necessary innovation to reduce time spent on household work is likely to be a cultural shift away from owning physical things and towards digital media. Arguably it&#x27;s already here - CDs, DVDs, games and books are all available digitally now, so we don&#x27;t have to keep shelves of media clean and tidy. Once people move away from owning art, pictures, plants, etc and replace them with digital versions instead then cleaning will become a trivial 5 minute job.
