There are definitely things that could stop that progress such as catastrophic events capable of eradicating all or most of the life on this planet, but lets just assume things keep going the way they are going... Why not?
Can I just point out that it's rather unreasonable to ask that question? Because if a catastrophic event actually did happen in the past, none of us would be around to ask said question.
