Moving the computation to where the data lives is the fundamental design move in object-oriented programming, and it got lost in the noise.

So a a big challenge in object-oriented programming is dividing the responsibilities because you're moving the computation to where the data is. Saying, "Well, this object does this and that object does that is a really critical decision because you want to you want the computation near to the data so that there's less coupling between them." which is a lesson that I I think uh kind of got lost in the noise. That's the fundamental design move in ob in designing object-oriented programs and I I think I stand behind that.
