If you want to be regarded as a oldie but goodie tech expert, be sure to watch Robert Downey Jr. next year as he hosts a new YouTube series about artificial intelligence.
Downey and his wife Susan, are executive producers. They own a production company called Team Downey. They describe the show as “a fascinating journey as we explore the exciting developments in the world of A.I. and glimpse into the future.”

Big Rep, a Berlin 3D printer manufacturer, is debuting a whole new type of bicycle tire. It’s the world’s first 3D printed airless bicycle tire. Unfortunately, the cyclists who want to try it will have to print it. The prototype is just a concept design.

You can be sure that I will be watching Team Downey’s presentation. Good idea, and about time! As for the bicycle tire…don’t know any cyclists who have a 3D printer in their back room!
