Do you enjoy climbing with others? Personally, I enjoy seeing the different beta on a climb, especially between different body types. It is interesting seeing unique approaches to the same problem.

What about when you try to solve the problem and you get stuck and can't? Or solve it but in a bad way that requires way too much exertion?

The point is to try to solve it yourself, then compare with an expert solution, and therefore learn how to improve.

If you're just blindly trying to problem-solve through trial and error without ever comparing against expert feedback, you're going to learn climbling extremely slowly...

Getting stuck is part of the game. It could take several sessions or it could take several years. It's what makes a climb truly hard, a "project".

It's an essential part of the sport - the satisfaction of using one's own body and mind to overcome the seemingly impossible.

If you never get stuck, how could you possibly experience it?

Games are no fun if they're too hard.

When faced with a challenge, you want to figure out as much as you reasonably can, and then learn what you were missing.

Struggling at the same problem for several sessons, or god forbid years, sounds like misery to me. I'd rather use that time productively learning, rather than struggling for the sake of it, because I refuse to learn from others.

You can use it after you do the climb to see if there is a more optimal solution.

As with any tutor, this could (possibly) help beginners.

Where the fun is is an opinion.
