I also think that being a little more cautious would have yielded many, if not most of the benefits we've received while avoiding many of the downfalls. Most of these companies knew their products were negatively affecting their users-- e.g. instagram and teen girl self esteem-- but actively suppressed it because it would inhibit making dump trucks full of money off of it. People who stand to make that money will ALWAYS say you're going to ruin everything if you do anything at all to impede progress-- that's ridiculous. The people that use their turn signal and drive within 10mph of the speed limit still reach their destination, and with dramatically less risk than the people that drive pedal-to-the-metal, tailgating, with that self-absorbed fuck-everybody-else attitude.
