BB cosmology is impressive, but at the same time problems with it have always been there and still are. Inflation is a framework which requires ever more finely tuned conditions to function, which frankly undermines the whole point of the conjecture in the first place. Instead of absurdly fine-tuned initial conditions, now you have absurdly fine-tuned energy curves for the infalton. Instead of a horizon and flatness problem you have... well you still kind of have those unless you adopt the unlikely potential energy plots for the inflaton. It's not a coincidence that other ideas ranging from MWI to Cyclic Ekpryotic are so persistent. It's an interesting and stimulating field of study and theoretical work, but it's still so far from anything we can test that it's sort just philosophy with some math. Take string theory, amazing tools for analyzing matters, but as a testable theory which actually maps reality? Eh...
