It doesn't work that way (inspire by Voltaire):

$ make life easier

Your life has been made easier: 70,500,000,000 dollars has been deposited into your bank account.

"There's plenty of challenge for anyone who wants to find it."

There are problems that haven't been solved yet and problems that can't be solved. Most problems can't be solved, since the majority of (our) problems are psychological (i.e. there are no axioms, assumptions, systems, etc to define this class of problem) -- the rest are impossible.

The problems that haven't yet been solved are actually interesting tho. The knowledge systems for these classes of problems are heuristic; i.e. a process of discovery and experience. The intention is often not to keep everything difficult but to keep everything knowable, which is contrary to the "don't make me think" principle of design.
