Bill Gates, Mark Zuckerberg and Twitter's Jack Dorsey promote computer coding in new video

''The first time I actually had something come up and say hello world, and I made a computer do that, that was just astonishing.'' 

Microsoft Chairman Bill Gates, Facebook CEO Mark Zuckerberg and Twitter creator Jack Dorsey are among the tech luminaries appearing in a new video promoting the teaching and learning of computer coding in schools.

Titled "What most schools don't teach," the video released online Tuesday begins with Zuckerberg, Gates and other tech icons recalling the time they got their start in coding. For some, that was in sixth grade. For others, such as Ruchi Sanghvi, Facebook's first female engineer, that happened in college. Freshman year, first semester, intro to computer science, to be exact.

Running less than six minutes, the video promotes Code.org, a nonprofit foundation created last year to help grow computer programming education.

"The first time I actually had something come up and say 'hello world,' and I made a computer do that, that was just astonishing," recalls Gabe Newell, president of video game studio Valve.

But it's not just tech leaders promoting programming in the video. Chris Bosh, of the Miami Heat basketball team, says about coding: "I know it can be intimidating, a lot of things are intimidating, but, you know, what isn't?"

Code.org  was founded by tech entrepreneur Hadi Partovi, an early investor in Facebook, Dropbox and the vacation rental site Airbnb. The nonprofit wants to address an oft-cited problem among technology companies — not enough computer science graduates to fill a growing number of programming jobs. The group laments that many schools don't even offer classes in programming.

"Our policy is literally to hire as many talented engineers as we can find," Zuckerberg says in the video. "The whole limit of the system is just the there just aren't enough people who are trained and have these skills today."
