you are becoming a computer engineer and yet you have much to learn, my friend technology is a product of development and vice versa, so you cannot have one thing without having another Technology is something evil!!!! Be awere my friends!!!!
Just kiding. Technology is important but not so much. The concept of development is often mistaken with economic growth. In order to have economic growth you do need technology. Like India and China, who are growing very fast. But development is something more complex, because it envolves many aspects. Like health, education, culture, wellbeing, equality...

I hope I've made my point.
