Keyboards and mice being supplanted by touch or gesture is only true for phones and tablets, which are new devices that really aren't equivalent to the general computing devices in the 90's: desktops and laptops. If anything, I'd say that tablets are just televisions that became small, light, and interactive, and smart phones are partly that and partly handheld gaming devices with multiplayer capability. Neither are equivalent to a computer (though they have computers built-in.) Of course, as a software developer, I've always used computers differently than the masses. The computers I need are far more powerful than anything they need.
