I seriously doubt the SLS will ever fly.
Space-X does everything Cheaper, Better, and Faster.
I seriously question viability of any future booster designed by NASA.

Yes, there is such a thing as NORMAL, if you have to ask, you probably aren't !

Agreed . . . Especially if certain "administrations" cut NASA's funding in the future.

Space-X could easily get a single use BFR going within a year or two by stripping down their current Starship project into a pure heavy lifter and not worrying about recovery. If NASA suddenly took the SLS budget and gave it to them to hire more techs and craftsmen, they might shave a few more months off of it. It just won't be quite as cool as the current project.
