Actually we do.
AI is not just for solving the hard problems in life. Like most people on /. here they are out of touch with reality.
What we need in AI is to make your life easier by doing all those things that you don't want to do, but need to do.
It should know who you are and all your preferences and plan a suggest things for you, like:
Plan a trip.
Book a flight
Tell you what you need to by,
Help you fix your phone email connection settings.
tell you what is good to watch.
Take your phone calls and screen them,
Go thru and sort all your emails and summarize.
remind you of important things and even buy stuff for you.
Keep track if your life goals and suggest paths and places to expand your life.
know how you feel and is able to help you through issues.
Find a good book to read.
What good is it to me on a day-to day basis, if it tries to solve a hard engineering problem that, maybe will impact me in the future, but not tomorrow.
That was the dream of AI when this all started in the 60's, and people seemed to forget all that and just try to get rich..
