At toy scale, yes, just like quantum computers. And since we haven't seen any news of working boson sampling with thousands of photons I assume that it stops working when you try to scale up, just like quantum computers.
New fundamental physical principles are at this stage required in any case, quantum mechanics and general relativity don't fit together, meaning that at least one of them need to be overhauled into something that explains the same observations but doesn't have quite the same maths. The lacklustre performance of quantum computers could be a hint to what needs overhauling.
