Yeah, that's what I meant. The gap between what's presented as ready-to-order and the actual practical feasibility of the product is so big, it wows people because they are still accustomed to presentations of actually consumable products.

And also your point: It is a company presenting a jet-pack to actually sell a premium back-pack under the same name.

They invested in the engineering of 1-10 jet-packs, to sell 200-2000 backpacks...
