How about 20 years ago? I saw Hinton's Restricted boltzmann machine and was dreaming of what we have today. Unsupervised learning, but in reality we got 10 years of supervised models before unsupervised was big.
Now I dread this stuff and avoid buying devices that live their own life and make decisions for me (and are always buggy), plus require a whole lot of maintenance. (Maintenance and fragility are what comes to my mind when guys show their raspberry-pi home contraptions off.)
