Someone invents something that works a certain way. How do they get that technology and make it smaller and better? Why couldn’t they just do that from the start? Like PS4 and a PS4 slim. Or PS2 and PS2 slim? It’s the same performance yet it’s smaller?

Because the technology isn’t there. To give an example, the current generation of CPUs have features as small as 7nm (nanometres, that’s very small indeed), which allows them to be smaller and use less power. Go back 20 years and the average feature size on CPUs was 20 times larger than that, while they ran significantly slower than today’s chips.
