I recommend reading the NY Times articles, it is quite long and some places surreal.
On the tech side of his startup, they wrote:
The company plans to use a technology found in self-driving cars called lidar — shorthand for light detection and ranging — as well as infrared sensors and cameras to monitor borders for illegal crossings, according to the three people familiar with the plan.
As as he sees it, according to those familiar with the plan, the technology can be used for many kinds of perimeter security, including military bases and stadium events, where it could be used to detect drones. Software would help the system figure out which objects to ignore, like birds and coyotes.
On the political side, they noted:
Luckey was pressured to leave Facebook months after news spread that he had secretly donated to an organization dedicated to spreading anti-Hillary Clinton internet memes.
[Luckey] contributed $100,000 to Mr. Trump’s inauguration, through one of his companies, according to Federal Election Commission records.
Luckey is getting more comfortable with politics. In April, he held a fund-raiser in California for Senator Ted Cruz, whose home state, Texas, has the longest border with Mexico.
And Mr. Luckey discussed the idea of using sensor technology on the Mexican border with Stephen K. Bannon, Mr. Trump’s chief strategist
Will be interesting to see how this evolves.
