Tech is where the money is. From the biggest titans in Silicon Valley to the little Square register at a roadside farm stand, business can't happen without technology. Every transaction and exchange depends on the work of IT professionals wielding a set of specialized and lucrative skills, and the market can't seem to fill some of the most important positions fast enough. Many adult learners want to know if they should pursue an online Cyber Security Degree, Data Science Degree or Machine Learning Degree. All of these jobs have a buzz in the IT field; CIO ranked all three in the top seven "Hottest IT jobs for 2017."

Self-driving car pioneer Sebastian Thrun has shifted his gaze to the skies, as his Silicon Valley online school Udacity launches what it calls the first "nanodegree" in flying car engineering. With companies from Airbus and Amazon to Uber throttling up development of their own autonomous aerial vehicles, Thrun believes "in a few years time, this will be the hottest topic on the planet." As usual, Thrun intends to be on the cutting edge of this emerging technology. The 50-year-old PhD computer scientist and former Stanford University professor, co-founded Udacity in 2012 and says the online school's self-driving car program has attracted 50,000 applicants since 2016. He expects the new flying car curriculum, which opens in late February and begins taking applications on Tuesday, to draw at least 10,000.
