Ya wish they'd speed it up, and then - - -
the complexities come to mind.
Designing those things, no matter who you are, seems like a chess game. The consequences of everything have to be considered, and the results considered, and those, etc.
And an unintended consequence usually ain't gonna work in your favor. A very long complexity tree.
So, it's slower than I'd like. And for good reason.
Sigh.
