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.
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
