In this day and age, we can't imagine a designer without a computer. It's almost impossible to function. Unless the designer is that rich or famous that she/he has an army of design slaves to execute their design ideas. And even then they will need the computer for basic communication. Still, there are extremes even in this.
Recently I had the opportunity to meet a German professor, who was trained at Ulm. He uses Indesign in a very different way. He actually codes the software to do exactly what he wants, when he wants it, so there is very little manual work. He believes that it is a machine, and hence built for the level of precision that we humans can never master. The human brain/hand is always liable to make a mistake. So why not use that precision to advantage? He rarely places objects manually in files, but has trained the software to carry out commands, all purely mathematically. The workspace looks different from a conventional Indesign screen. Of course, he can do all this because he has miles of experience behind him, is a true master of the grid, and understands coding and computers. It does make sense, to actually make full use of the computer as a machine. He gives the commands, and Indesign obeys them, laying out the publication. The computer is his slave.
At the other end of the spectrum are some students of typography in Jaipur. A friend visited them recently. There are a few in the class who have never worked on a computer before. To the extent that a couple of them don't know of the very basic computer interactions. For instance, they had no concept of a drop-down menu. The teacher first had to teach them that. It is akin to teaching a student how to hold a book, open it, or how to use the pencil. This means that we take our relationship with the computer for granted. We intuitively know where the drop-down menu is, where the buttons are, and we can react accordingly, without thinking. But for a newbie, who perhaps has never worked on a computer, it can be learning from scratch.
The computer has become the tool most fused with the human brain and hands. But it still can't substitute the real tool of the human mind. Designers need to develop that tool first, to make best use of other tools. Only the intellect can think of ideas, concepts, and weigh them. Creative thought comes from humans, not machines. Microsoft Word can't write the Ramayana by itself.
Working on the computer should not become working for the computer.
