I know that because that is what Elon Musk and other SpaceX engineers and have said. They have explained this in multiple presentations and interviews over the last 5 years. This is not a mystery. I am not speculating.

There is a whole community that has been following this project since day 1. There are people filming the production site every day. The analyze every part they see and try to figure out what changed. Some people in the community can get questions to Elon Musk and others.

The reason you are getting down-voted is that you seem to have not studied it at all what SpaceX is actually doing, and simply jump into the comments and make strong statements that what SpaceX is doing is wrong.

And your justification for this opinion is totally unconvincing for anybody that has actually studied the problem.

Its really not about believe. Its a simple fact that everybody has acknowledged.
