Comparing it to mobile phones in a negative kinda surprises me. You really think mobile phones are a net negative? I actually have trouble seeing how my current job was done before mobile phones... Then when the whole covid thing came out, we started using teams. What used to be 12 guys in a conference room, discussing plans, became, me sitting on the job, discussing the plans, while actually looking at the site conditions. While I'm sitting in the car onsite, I can mention something they missed, and engineer can adjust the plans, live, on screen, while getting feed back from others, and discuss it. It also changed an entire lost day, into a 2 hour or 45 minute thing.
