As someone who doesn't work in advertising but is insterested in the space, I find your comment interesting but it doesn't help you are not providing much data for your hot take either. You mention Kickstarter, but looking at the list of crowdfunded projects, most of the successful ones were quite a while ago, if anything the most recent ones looks like scammy crypto coins, which would suggest advertising works rather for bad projects, a net negative.
