The 4 fields of Industrial Design

Here is an interesting read from core77.

The comments make for some interesting reading. Im too much of a noob to comment myself, all sides have good arguments.

In summary the writer says there are 4 fields of ID.

Commercial - Where you design to make money
Responsible - This is where designers want to make something that will benefit society, I think this is what most designers want to do but get stuck in the commercial side coz thats the way life is.
Experimental - This is more art than design. It pushes boundaries but probably isnt the most practical solution to a problem. Actually there probably wasnt a problem in the first place.
Discursive - This is like Experimental design with practicality. So it could also combine elements from Responisble and Commercial design.

Actually they all can 'overlap' as put in the article. However if you read the comments you see that many people disagree with this categorization of design, alot more seem to like it though. Like I said at the start Im not sure about it all.
