We see a future where operating systems are significantly different from the ones today. Each system will know its user deeply, and be hyper-personalised to each individual. Interfaces will adapt to our context and needs. Suggestions will surface naturally, and once we confirm an intent, agents will execute on our behalf. The system will handle the non-essential for us, allowing us to focus on what truly matters, which will be different for every person. Unlike today's one-size-fits-all solution, a billion different operating systems will be rendered for a billion different people.
