Strangely, computer science is best when it's a secondary interest of a person. Based on my observation, people from other fields coming to comsci have created more interesting projects than the one who first entered the field. Of course, except those who invented great programming languages and protocols. On economic level, creativity comes from broad knowledge and perspectives mixed with tech skills.

There will definitely be a need for computer programmer .. with great creativity and other knowledge. This is rare! Look around 97th percentile programmers today, their knowledge is such narrow.

Lots of room for innovations, though is also limited by poverty status. Creating boring thing, developing boring tools is still the norm of need, so it may seem saturated.
