Evolution of programming

• Transistors: on or off.
• Logical gates: and/or/not (knitted together).
• we called such an on/off device a bit.
• punch-cards (hole or no-hole)
• 0 and 1 values
• More complex instruction represented by numbers between 0-255 that represented by 8 bits we called a byte. (2^8 = 256). Assembly.
• Languages such as C that can be translated to the lower level instructions using a compiler.
• Higher level languages such as Python using an interpreter - it is like a simultaneous translator.
• Writing human(ish) language - AI.

• We still need to learn how to talk to it so it will do what we want.
• We need to know what we want.
