I agree they are orthogonal, but that does nothing to support the point that analog computers could be even more powerful than quantum computers. You haven't really explained your second point, but assuming it's true, you'll only be able to "recognize the direction" within your margin of error. Your noise floor will be way above the required precision to explore a high-dimensional space. Analog computers never achieved common use because of noise and lack of practical error correction. Even the human brain evolved to be mostly digital and we almost never focus on being exact.
