And yes, we've seen big changes in consumer technology,
- from desktops to laptops to mobile devices with more power than big computers.
- from dial-up internet connections to wi-fi everywhere.
- from typing letters, and learning to fax from the computer, to ever-present email and social media.
- from adults teaching children, to children teaching adults.
Thanks to all of you for being with me along the way. It continues to be an interesting field, although my search for better knowledge management, intelligent computing, and low-cost internet access for everyone still seems out of reach for many.
