A couple of years ago, Ashok Goel was overwhelmed by the number of questions his students were asking in his course on artificial intelligence.
Goel teaches computer science at Georgia Tech, sometimes to large classes, where students can ask thousands of questions online in a discussion forum.
With a limited number of teaching assistants, or TAs, many of those questions weren’t getting answered in time. So, Goel came up with a plan: make an artificial intelligence “teaching assistant” that could answer some of students’ frequently asked questions.
In 2015 he built Jill Watson, his AI TA — named after one of the IBM founders, Thomas J. Watson.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
