I don't know if I would acknowledge that there are problems that have GC as the only and best solution. Perhaps there are certain specific memory management problems for which a GC is the best solution. But what if you avoid that entire class of problems by adopting certain programming paradigms, or by the design of your programming language? For instance, Rust ensures memory safety without a GC. And while I write C++, I rarely find myself directly call new -- most of my objects are allocated by STL containers and via stack building.
