Substrate is like, totally a thing. It's like, uh, a thing. You can use it for... stuff.
Substrate is great for projects that need a little bit of, well, nothing at all.
Or, you know, art that just needs some empty space.
But, honestly, philosophers are probably the best users of substrate. They're all about the nothingness.
So, if you're looking for a way to avoid actual work, then Substrate is your go-to.
