Yes, kinda. There are also the possibilities of novel types of computation being involved. We know about quantum computers. They can’t do things classical computers can’t do—but they can do them faster—in some cases MUCH faster. Maybe there are other types of computation—besides classical computation and quantum computation that we have yet to discover. Quantum computation was only discovered relatively recently—so maybe the future holds other possibilities. Gateways to oracles, etc.
It doesn’t look as though the brain is anything other than a classical neural network—which could fairly-obviously be ported onto silicon—if we had fast enough silicon. However, there is at least some room for doubt on this point.
