The same when I learned about the internet.
Now, I'm looking at things like Asahi Linux or the people building operating systems and compilers, and I do find them fascinating, and I'm always thinking about starting to hack on something new so that I can create something and learn and create a bit of magic myself, but I never sit down to do it.
Is anyone else feeling like this? Like you _want_ to do something with the things you already know, you want to learn, you want to demystify how things work under the hood by building something for the fun of it, but never start?
Any ways to overcome this lack of motivation and drive?
Thus, motivation comes down to find something meaningful/purposeful to work on, and then wanting to do the best implementation possible for that thing, whatever it happens to be.
Maybe building self-hosting language/compiler, or a toy linux-like kernel, or a physics engine, games then publish to itch.io, a small numpy-like library that can do autograd, whatever.
Once you start it really is hard to stop.
