I think there's more nuance to it than that. I could not build any of her "shitty" robots. They were almost certainly a learning experience. That she also managed to entertain and even inspire others through that learning experience is a great accomplishment.

She shouldn't be so hard on herself. If calling the projects "shitty" gave her permission to fail, well, failing is also a part of learning.

Now she's ready to progress to "useful" robots—or other projects altogether. That makes sense.
