> Just fill needs that you have. Don't like how something existing works? Fix it. Think you can offer a better version of an existing idea? Go for it.

While I don't disagree with this point, what it often leads to is developers creating developer tools, which is a crowded and competitive area.

There are fields out there that are crying out for tech solutions because they are lumbering dinosaurs that haven't changed with the times. One example is the maritime industry. It's amazing how much is still done with pen and paper on a ship. True, there is often a reluctance to adopt new tech, but the younger cohort of mariners are far more eager and receptive to tech solutions than the previous generation.

My suggestion is to look for those industries and talk to folks in those fields about their pain points. The bar may be so low that you could step over it.
