Not necessarily. Making a great product would only attract a younger audience more and make the videos far cooler. But that takes a ton of time. Way more than just painting a large cannon and strapping some elastics to it
Mark clearly tries to only deliver a minimum viable product for a single shot rather than an actually functional product.
He falls under the “shittyrobots” engineers that don’t just make shitty robots for fun, but because they can’t actually make non shitty robots which accomplish the desired goal of their video well. Some people such as “I Did A Thing” don’t try to hide it and make it part of the content. Mark is in the twilight zone of pretending he’s engineering complex stuff while not actually doing that.
