POST R&R

Designers do UX, beyond just GUI.
They make pretty things that have a reason and a purpose, not just pretty things.
Because "design" and "visual" or "graphic" aren't the same thing.

Developers are creating living, or at least organic, things - not merely functioning (moving) things.
For this, their attention seems to be extending to each user's individualized environment.

Recently, the work (in Korea) that planners used to do - analyzing users and understanding requirements - is being done by designers.
The seamless interactions and on-demand interfaces designers used to do are being handled by developers.

Planning? Well, where isn't it - planning is what everyone does.
In the past, what planning did was really passive task management or acting as a proxy for inefficient communication between function holders.

In the post-R&R world, planners seem to be either disappearing or moving from project manager to product manager - and that's why planners need to know Python or R, and at least understand (if not handle) deep learning.

That way, designers and developers can deep-dive into user and network communication.
