ELI5: how did the TV, computer, and telephone have such a vast reduction in size and are able to do you so much more at a much higher quality?

The main technology that makes all of that happen is the transistor - a little gate that can let electricity through or prevent it from flowing through.

Currently, they are as small as single-digit nanometers in length. Thats significantly smaller than a human hair. The technology needed to be able to manufacture that level of precision is not something we've had access to for long.

Our ability to manufacture those transistors at smaller and smaller sizes is ultimately what has been the limiting factor. Over time, we've seen these shrink at a pretty predictable rate - and the advancements made in every sector that relies on them have improved along with them.
