Looking at history, anything in its first few iterations costs insane and stay as luxury or is sold at massive loss. Once the research goes on for several years, the costs keep coming down first very slowly and then in avalanche . The question always remains to which one can continue “selling at a loss” long enough to last the point until the costs continue going down while people are used to paying standard price(see smartphones), or the product is so market dominant that competition does not have resources to compete and cost can be raised(see Netflix).

I paid money to Amazon for most of a decade before they had a profitable year.
