Let the laws of physics do the recurrent math for you. Analog RNN computers would be very interesting, but they would first setting in stone the basics of the algorithms we use. We are still only beginning to explore the algorithm space, and this requires a flexibility that analog computers (or even ASICs or FPGAs) don't provide. It's still not clear whether the future of AI will even involve neural networks at all. Intuitively, they seem so inefficient.
