Over the past few years we've seen so many industries undergo a massive shift due to a new player in the field who utilized software in an innovative way, and yet I'm sure there are tons of industries that still operate in a 20th century manner and could be drastically changed with the right idea, what are some of these industries?
The jail system in the USA? ISPs. Automotive. Lighting (like, lightbulbs). Recycling or compost for individual homes; landfill solutions. Replacements for plastics in food packaging. The banking system (it's hard to transfer money between people's accounts, easily, as many use third-party apps to do this). Some of these are so hard to make changes in due to hard lobbying to maintain monopolies, which Google Fiber (building lines) and Tesla (sales through dealers) are experiencing.
I definitely feel governments could use major updating, in making data accessible, automation of their processes (e.g. lawsuits, immigration, etc.), the 911 system, etc. Enabling easier recording/organizing of decisions and processes made by everyone. It all feels so closed to me. Take for example open data from NYC to find where the most parking citations are handed out[1] (and then submitting requests to rectify the situation). I'd love to help in an effort like this because I think it would be very valuable for the people.
