It is an engineer's job to go from vague description to detailed design. Better tools make the process easier, but also expand the scope of what we consider possible. So we think in terms of bigger projects, which also means we pay attention to fewer details at that level. The engineer's job is to make sure those little details you forgot all work together in a cohesive whole. Engineering will never be obsolete. It will just change thanks to better tools that alter what we think of as small details.

PS - I wonder how much detail tomorrow's engineers will have to manage.
PPS - Probably about the same, but they won't look like today's details.
