If you're talking about hardware, I don't think anyone makes anything as low-level as a Boolean gate anymore. Maybe you can still buy an Arithmetic-Logic Unit (ALU), but most likely you have to get the whole CPU now.
We don't include the Boolean operators for the sake of simulating hardware; we have them to support complicated test conditions in IF and friends.
In my youth the best scientific computer (≈$2M) was the DEC PDP-10, which had all 16 Boolean operators as machine language instructions. :~)
