Earlier quoted context omitted.
Im the opposite, I think things like this are the most important things they can be doing. Empowering the next generation of innovators, empowering people. People are who do those experiments...
Empowering to do what? If NASA spends all day making comics then will attract people that like making media about rockets and not rockets themselves. If NASA makes cool rockets then they will attract people that naturally align with their mission of making cool rockets. If you do [THING] get good at doing [THING] and you will attract people that also want to do [THING].
How does anyone hear about the thing you're doing or making? How do people figure out how to get involved? How do you attract different people(women, POC, etc) to your thing if they aren't already represented?
People don't just magically know about something that's interesting to them. They have to discover it.
Tons of very influential or popular figures only took their path because of things like comic books(art) from NASA. I wouldn't be an engineer today if it weren't for stuff like How It's Made or Bill Nye. Representation matters.
