Is every finitely generated simple group $2$-generated?

This happens to be true for finite simple groups and for Tarski monster groups, but is it true in general? I do not know how to prove that, but neither do I know any counterexamples.

I haven't read it thoroughly enough to understand the construction, but this 1986 paper by Guba constructs a finitely generated simple group all of whose $2$-generated subgroups are free, and which is therefore not itself $2$-generated. From the introduction it seems that the question you asked was open until then.
