Potential minor problems I would want solved: 1. When I have very interesting discussions with someone I wish I had it recorded so I could post/share it online. I am thinking just daily stuff without having to sit in a room together and do a podcast. This can KINDA be solved by livestreaming nonstop but that's far from ideal and does not have mass appeal.
2. A more modern way of finding jobs - I really believe there's a lot of improvements to be made here esp in Denmark. We use Jobindex, LinkedIn and Jobteaser primarily and all services seem ineffective. Probably just a university student problem. Regardless, it does not sound like an interesting problem to solve like the other ones I mentioned above.
3. Speeddating. I don't struggle with going on dates or picking up girls IRL but it would be more fun if you could just click "QUEUE" on your phone and it automatically sets up a blind date - maybe this actually exists already? Sounds so fun.
