Ha! Your wife is absolutely right! Artificial Intelligence is a complete waste of time and energy.

> 4 NANDs and an inverter give you a D-latch that lets you synchronize your circuits to the clock signal.
A D latch would be enabled all the time the clock signal is high, so it is not suitable for synchronizing your circuits to the clock signal. What you need is for the device to store the input at the instant when the clock signal goes from low to high. (Using the tech terminology: the 4-NAND D-latch has level triggering, while for the clock you want edge triggering.)
