MODERATORS
On a high level, all simple machines.
The wheel
The lever
The pulley
Etc.
All other machines (except maybe things like computer chips) are just a variation of simple machines, or a combination of them.
Wheels have definitely changed a lot though.
Wheels are fundamentally the same, mechanically.
How they're made changes, and what they're made of changes, but they are fundamentally the same mechanically for how they function
I would argue that Wi-Fi is also fundamentally the same as it was invented, it's just network packets sent over high-frequency radio waves, but there has been a lot of changes in specifics. It's the same for wheels, while the fundamental principle is the same, the differences between a wheel 4000 years ago and today are staggering.
I like how this old teaching tool doesn't include an electric circuit.
It can if we include things such as power generators
