You are right
You are a broken record. You think everything invented worked perfectly on the 1st attempt. Everything takes much R & D. Read the history of oil. People were laughing at people trying to drill for oil in the ground, then when they proved it would work, people said if you get oil out of the ground you will put whalers out of job. This is how we keep making improvements and yes that costs money but when scaled up prices will drop.Until you understand that you will always be singing the same old song.
