I feel like the current application paradigm cannot scale, and will only lead to further fragmentation. We all have 100+ different accounts, and 100+ different apps, none of which can interact with each other. Most people seem to think that AI will solve this, and make natural languages the main interface to AI, but I don't buy it. Speech seem so antiquated in comparison to what can be achieved through other senses (including sight and touch). How do you imagine humans will interact with future computer systems?
