It seems that in the 1980's, when I was first introduced to the Big Bang as a child, the experts in the field knew then there were problems with it, and devised inflation as a solution. And today, the validity of that solution is being called into question by those same experts:

The dominant Big Bang theory (the Lambda CDM model of inflationary cosmology) today has evolved significantly from the Big Bang theory of the 80s. For example, the realization in the late 90s that the expansion of the universe was accelerating rather than decelerating required significant changes.

And yes, we know that we do not yet have a perfect understanding of it yet, and that more tweaks and modifications are needed. But I think it is inaccurate to talk as if the big bang model needs to be thrown away. The situation is more like a jigsaw puzzle where we have a good idea in general what is going on, but there are still missing pieces.
