These are awesome and thoroughly enjoyable lectures, they really fill in the gaps between the transistors and the cpu architecture ie. the PC, ALU, registers etc.
At 1:06:50, I feel that the output is not correctly mentioned because s0 refers to the second digit of the input while s1 refers to the first digit. Hence, the truth table should be: 1. 00 -> D0 2. 01 -> D1 3. 10 -> D2 4. 11 -> D3
Can any one explain why tri state buffer is preferred in CPU/Memory data, as both control signals are high it will be in treble. why don't we go with multiplexer here?

F= A+BC
Can some explain how it resulted from second last step?
You can group A'BC to A'(BC). With this knowledge A + A'BC = (A+A').(A+BC) and (A+A') = 1 so solution of the equation is F=A+BC
