Wood has always been decomposable by fungi. The idea that there was a lag in evolution is a once-prominant myth that has since been disproven.
Plastics are not a single chemical. If anything it's more of a characteristic of a wide variety of polymers which are typically synthetically derived from petroleum are extremely varied. Even if fungi/bacteria eventually evolve the correct enzymes to break down some of the plastics, it's foolish to think all plastics will be solved by evolution. Especially since many of these enzymes result in other microplastic compounds instead of full decomposition.
It's also a little rash to hope for it given how much of the world's infrastructure would be threatened by such a development.
