I don't know how you can be so sure about something if the answer's "yes" to every question, but you do.
And that's the key. I've never really had any problems with robots being able to solve puzzles. I've only had a few that have worked.
The key to understanding a problem is understanding it, because it is a human problem that we all need to solve, but that's where you start to learn more.
I've never had problems that are not human-level. But when I do get stuck, that can be frustrating. I don't think it is the right way for robots, because it can't be done.
So, if we're not able to solve this mystery, we have a problem.
And I'm pretty certain it's going away, so that means it's time to get out there and do it, and do it well.
