Learning and using the tools to become multiples more productive is relatively hard, still.
In programming, most people still struggle with syntax. The few that get past struggle with conciseness. The few that get past end up managing everyone else instead of solving problems. LLMs move maybe a few percent up the ladder, but hardly enough to matter atm.
In other fields, there’d need to be breakthroughs, otherwise it’s literally scale. Ex: manufacturing is labor intensive and/or capital intensive, w/o a breakthrough like… robots.
Laptops without access to the internet are far less productive for most people. There are so many examples of tablets and smartphones with internet connectivity replacing other machines and/or making them resilient. Point of sale systems, hotel room key, ticketing systems, translation services, navigation from any point to any point, whether it be walking, bicycling, driving, or public transit.
