Of course, but we're not anywhere near the physical limits. An analogy is that it's clear that molecular nanotechnology is feasible, and consistent with known physical law, even though we don't know how to engineer MNT systems.
The "extrapolation of exponential growth = 'Singularity'" idea is a really crappy argument, and you shouldn't give much weight to it. For me it comes to two postulates: 1. AI is feasible. 2. When AI arrives on the scene, large changes are in store.
