There has been a lot of innovation - but it is focused to some niche and so if you are not in a niche you don't see it and wouldn't care if you did. Most of the major things you need have already invented - I recall word processors as a kid, so they for sure date back to the 1970s - we still need word processors and there is a lot of polish that can be added, but all innovation is in niche things that the majority of us wouldn't have a use for if we knew about it.

Of course innovation is always in bits and spurts.
