Uber, Airbnb, and other companies are riding the wave of the "sharing economy." If we are to believe economic gurus, it is the wave of the future. The whole concept originates in the idea that anybody can do anything. DIY stores may have started that trend. Instead of hiring a qualified professional who possesses the skills and the tools needed to perform a job, people go to the DIY store, purchase the materials, the tools, and then spend hours figuring out how to do the job. Most of the time, they paint themselves into a corner. Sometimes, they end up in the hospital, except, of course, if they decide to reduce the fracture themselves and to do one more run to the DIY store to purchase some plaster to make a cast.
So, today, you can rent your sofa for one night to a "couchsurfer" or give El Chapo a ride to the airport. If this trend continues, soon anybody with a well-secured basement or a "red room" will be able to offer their service to house a few inmates. Calling 911 will connect you with Rita, who, from the comfort of her living room, will be able to dispatch a few armed guys from the neighborhood to deal with your intruders, or to try to negotiate an acceptable fee for some hose-owning neighbors to come and extinguish your house fire.

Some of this data ends up on the YouTube video that shows you how to change your refrigerator lamp yourself, so knowledge does not have to be memorized anymore. What we need to do is to teach students to follow directions, and they will be able to do anything... Unfortunately, the ONE THING my students have the most difficult time doing is to follow directions.
