After the excitement of electric cars and space technology, Tesla Motors Corp. (TSLA) CEO Elon Musk’s next company might just be a tad boring. In a tweet Saturday, Musk, who appeared to be stuck in a traffic jam, said that he was going to build a tunnel boring machine “and just start digging.”

That assertion might seem like a joke except Musk followed it up with another tweet announcing a name – The Boring Company – for his new venture and a proclamation that he was “actually going to do this”. He also changed his Twitter bio description to include “tunnels (yes, tunnels)” in a list of his ventures.  

Considering that this announcement came from a man who has had a hand in reinventing three industries – financial services, electric cars, and space technology – it is likely that he was not joking. Musk’s announcement also comes right after his meeting with President-elect Donald Trump, who has pledged to invest $1 trillion to upgrade America’s infrastructure.

Musk’s participation in Trump’s plan might turn out to be mutually beneficial for both parties. Musk’s previous ventures have gotten off the ground thanks to a combination of government support and subsidies. At the same time, his companies have kickstarted new industries at a time when established companies in the field were unwilling to take risks. (See also: Hyperloop System Vs.

Musk has already put forward the idea of a Hyperloop transit system that uses underground tunnels with low pressure to transport passengers at high speeds in pod-shaped vehicles. His current plan would dovetail well with that concept. But Musk might be stretched too thin, if he takes on the task of building another company. He is already CEO of two companies (Tesla and the privately-held SpaceX) and chairman of SolarCity Corp. (SCTY), a solar company that he recently merged with Tesla amid investor opposition.
