Looking at modern technology…
Caveman would ask: ”Can I touch it?”. And they made it. Almost everyone owns a smartphone, no buttons. All touchy-touchy. Even more, respond to shakes, pinches, rotations…yay.
Caveman would ask: ”Can I carry it around?”. And they made anything wireless. Cool af.
And lately, as stupid people try to talk to devices, asking for what they want instead of operating them, science complied with this, and it is assiduously working on making us look less retarded when speaking to phones and computers.
Cheers Ok Google, Cortana and Siri! We appreciate your work on making us look less savage every day.
