Artificial light can be manipulated to whatever intensity you desire. Today we can create spaces that closely match that of natural light. Artificial light should not replace natural light where possible, but cannot be overlooked.
There is a place for artificial light, however energy efficient homes use more natural light and thus have less need for artificial light.
Bottom line, you want good lighting in your home and both natural light and artificial light can make your home much more vibrant and welcoming.
