> The innovations in the blue color field might seem trivial but they are absolutely real. Not an innovation in the field per-se but nevertheless an innovation that improves the daily routine of many people working in the field is the mobile phone and especially the very cheap data and voice subscriptions (compared to 10-15 years ago, say). Just yesterday I had to call a locksmith at my apartment so that he would fix something at the bathroom door. During his entire intervention (45 minutes - one hour) he was also on his phone (via headphones) talking with one of his other coworkers and at some point with (what seemed to be) a close relative. That reminded me seeing the same scene with a public cleaning worker from our city talking with someone close on a phone (friend or relative) while raking the autumn leaves in front of my building. Again, it's not something that improves their "productivity" or anything like that but imo it reduces some of the alienation of being cut off from your friends and close relatives for at least 8 or 9 hours a day because of work.
