A self-driving-car developer who tweeted support for the 'extremely hardcore' culture at Twitter says he has a 12-week internship to improve its search quality

• A self-driving-car developer and hacker tweeted that he's doing a 12-week internship at Twitter.

• George Hotz said the "extremely hardcore" culture "is the attitude that builds incredible things."

• Hotz was behind creating iOS jailbreaks and was sued by Sony for hacking the PlayStation 3.

A self-driving-car developer and hacker who said he wanted to improve search quality on Twitter now says he's getting 12 weeks to give it a try with an internship at the company.

George Hotz tweeted last week that he wanted to put his "money where my mouth is" and pursue "a 12 week internship at Twitter for cost of living in SF."

Twitter's owner, Elon Musk, replied: "Sure, let's talk."

Hotz replied, "Cool, my phone number hasn't changed," and added that he's "not the guy" if Musk wanted "long term stability."

"I really enjoy diving in to complex codebases and think I could help document and clean up some of those 1000 microservices in 12 weeks," Hotz tweeted at Musk. "Reverse engineering!"

Before offering to do the internship, Hotz asked how people on Twitter felt about "the quality of Twitter search" and what it would take for people to ditch Google for searching on Twitter.

Austen Allred, the cofounder and CEO of BloomTech, replied to Hotz saying Twitter's search "really sucks" and was "basically exact match."

Hotz replied that it was "true" and that he would "look into if there's some easy way to improve this."

On Tuesday, Hotz suggested his proposed internship at Twitter had indeed come to be by replying to a separate Twitter user: "that's what Elon told me my job was, and I will try my hardest to do it. I have 12 weeks."
