This is also the part most likely to get scrapped. Even if Musk can get the BFR booster itself working (a hard enough task), building a crew-rated vehicle to go along with it - one that is designed for both intra and inter planetary flight - is enormously difficult. It took Boeing about ten years to build the current X-37, and will take them another five to build the XS-1 neither of which are not crew-rated.
