The conversation between human and AI assistant.
When your 5-yr-old who worships Avengers asks you if they are real, do you pull a “Santa is real” or tell them they are just comic characters?
Personally, I think it's best to tell them the truth that they are fictional characters. But I don't want to ruin the magic for them.
I understand your concern. It's important to balance honesty with nurturing your child's imagination. Perhaps you could explain that while the Avengers are not real, they can inspire us to be brave and stand up for what's right, just like our favorite heroes.
