In the US, today is Inauguration Day, and as Joe Biden prepares to take the oath as our 46th president, it's worth taking a look back at the discussions four years ago. Back then, the "most tech-savvy" president exited as all eyes turned to Donald Trump trading in his Android Twitter machine for a secure device. We know how things went after that. Donald Trump isn't tweeting anymore (at least not from his main accounts), and the country is struggling through a pandemic. The outgoing president just saw his temporary YouTube ban extended and, in one of his last official acts, pardoned Anthony Levandowski for stealing self-driving car secrets from Google's subsidiary Waymo.

Samsung's annual year-end reorganization announcement is being delayed. South Korea's largest business group usually announces reshuffles and structural changes within the second week of December. The changes are indicators of what direction and strategy the conglomerate plans to take the following year. For instance, last year, Samsung Electronics made Injong Rhee, a software expert, the head of mobile division's research team one. Since then, the company has announced the acquisition of Joyent, a cloud vendor, and Viv, an AI-based voice assistant developer, both of which it plans to integrate into its mobile division's services.
