> The line that separates technicians from designers and scientists is much blurrier in computer science etc. than most other fields. I think that the GP provided a reasonable explanation for this situation by saying that the "field is less than a century old". If you go back in time you are more likely to find one person inventing a new brick, designing a house with it and then building it. But later when the body of knowledge was too big for one person, specialization started (the same happened in medicine and many other fields). And actually it is already happening in the IT area. Just several years ago it wasn't uncommon that a game or any other non-trivial piece of software was created (including some clever "inventions") and marketed by one person.
