Erlich administers the Hacker Hostel, a tech incubator where Richard, Big Head, Dinesh, and Gilfoyle live and work in exchange for 10 percent of their potential businesses. Erlich clings to his glory days, when he sold aviation start-up Aviato, a move that, at least in his mind, qualifies him to be a svengali lording over other tech nerds. He still drives a car emblazoned with multiple Aviato logos and smokes copious amounts of weed.
In Fiduciary Duties, a drunk Richard makes Erlich a Pied Piper board member, a decision he later regrets, only to later see Erlich's value to the company and re-offer him a seat on the board.
In Two Days of the Condor, it is revealed that Erlich no longer codes due to carpal tunnel syndrome.

"No, no. You listen! You're always going on and on about how this is such a good neighborhood. Do you know why this is such a good neighborhood? Do you know why your shitty house is worth twenty times what you paid for it in the 1970's? Because of people like us moving in and starting illegal businesses in our garages. All the best companies: Apple, Google, Hewlett-Packard, even Aviato. All of them were started in unzoned garages. That is why Silicon Valley is one of the hottest neighborhoods in the world. Because of people like us. Not because of people like you.
