Some of the things I've learned at university are pretty interesting and fun to play with. Now, notice the "fun to play" with part. Some thing require a lot of investment (both money and time) in order to be learned. So, I believe it's not unfeasible to want to start a company so that you can fund your curiosity and learn the new things. The company itself might fail, or might not, but I believe as long as the purpose was to learn something new, failing is not as bad. If you start a company thinking this is the future, and you put value in making money as opposed to learning, then failing is losing.

In an ideal world, that would be possible, yes. But a company does need to make some money, even if only to pay its founders for their time. That money can come from investments, but if you start a company just to learn new stuff you'll have a hard time finding those.
