Every day people are thinking of new and better ways for people to go about their day to day activities. Whilst not everyone might not be a tech-head, or into gadgets, two of the biggest inventions in the last 20 years have certainly went mainstream and changed the world (and not just the technology world) forever.
These of course are the mp3 player and the iPhone. Whilst the first commercially available mp3 player was developed by SaeHan, these products really became mainstream with the release of the iPod. These are just two examples of how a somewhat simple idea, to carry digital audio files in your pocket, and to have a phone that is also a mini computer respectively, changed the world forever. https://www.reddit.com/r/TalkingMoney/comments/9a8dzh/assistance_with_invention_ideas/
