It can be very rewarding to jump right into a new creative project (e.g. cellular automata, drawing, etc) without any knowledge of what's already been done before. When you approach a something from a clean state perspective, you won't have any references of what's what, and all of your discoveries will be the result of your own creative experimentation. If at some point you feel like you've reached a limit to discovering things, you will naturally become curious about what other people have done -- to see what else is out there that you didn't find on your own. Only then do you see the sort of stuff that's already out there, and it's way more exciting, because you appreciate it how difficult it was for others to reach unfamiliar states you didn't reach on your own.

That same bewilderment might not happen if you read about all the amazing things that already exist before you even get started. If you read or see too much of what's already been done first, you might just end up feeling starting from scratch is boring, because it isn't as interesting as the more advanced stuff other people had already done.

This is pretty much my feeling in every side project idea I've thought up :D

You may not have intended to come across as rude, but you did.
