The difficulty of predicting difficulty

Math and logic are the foundation of computer science so I think they will always have an easier time with logical tasks and games than art.

Difficulty can be subjective and may vary from person to person.

Tackling a new task or problem often requires experimentation and learning through trial and error but that depends on everyone's prior knowledge and experience, I guess.

I've gotten a lot better at guessing what the hardest part of implementing my ideas will be.

Now I'm right about 15% of the time. :)

Completely different to what I expected. Made me laugh and then made me think. Well done, and I also agree with your perspective on this.

Yes, exactly. I've said this many times lately. We just cannot know what we don't know.
