Literally no expert said that SpaceX would fail at reusable rockets. The science behind rockets is literally decades old at this point. The U.S. designed reusable rockets back in the 1980s and never built them due to budget cuts. Experts said they weren't sure if the cost of developing reusable rockets would be financially sustainable, given that SpaceX started while the U.S. still had a functional space shuttle program. And...absent the NASA R&D contracts, SpaceX would not currently be sustainable on the basis of commercial launch activity.
