Why do you think your computation resources have to grow faster than the speed of light? That isn't even a dimensionally consistent statement. Are you assuming that the FLOPs per unit volume per second will be constant? Or that the amount of energy per FLOP will be constant? I don't think either of these assumptions is reasonable.
