For memetic reasons I immediately wondered if the same cognitive apparatus might be repurposed to identify hotdogs. No doubt specific areas of the brain are electrically involved, and monitorable via electrodes or more invasive probes. This suggests an opportunity to bring to market an efficient, self-cleaning, content filter engine employing a redundant array of cats; then further observe that caudal repositioning is an output property of tensor cats, making such an array the perfect vehicle to unlock the broader field of Feline Learning, with obvious opportunities for tail optimisation at runtime and dinner time.
