Take a peek in boardrooms across America and you'll find a lot of Baby Boomers at the helm. Not for long.

As I mentioned in my post yesterday of leaders in many fields who are Gen Xers, we've been underestimated all our lives. Today, I'm sharing a list of 10 business leaders who have invented new technologies, pioneered new fashions and are running some of the biggest businesses in the world.

Someone forgot to tell these business leaders they were slackers, I guess.

Elon Musk - Born in 1971, he co-founded PayPal and Tesla Motors and founded SpaceX, the company that plans to usher in the true era of space exploration. Space X's first launch vehicles were named in honor of the Millennium Falcon, the spaceship every Xer wanted to fly in as a kid.

Laura Alber - The CEO of Williams-Sonoma, Alber was born in 1968. She's one of the highest-paid women in the world. I wonder if she used to pore over catalogs as a child, wondering how they got those bizarre names for colors.

Jack Dorsey - Born in 1976, he's the youngest of the Twitter founders (Biz Stone was born in 1974 and Ev Williams in 1972). Dorsey just returned to Twitter as CEO and stayed on as head of Square, which he also founded.

Tim Armstrong - Before being named CEO of AOL, Armstrong was cofounder of Patch Media. Born in 1971, Armstrong also once was president of Google Americas. He also owns a team in the National Lacross League. Betcha didn't know that even existed.

Daymond Garfield John - Born in 1969, John started the FUBU clothing brand by selling hand-sewn hats in front of the old New York Coliseum. He's now a shark, investing in other entrepreneurs on Shark Tank.

Michael Dell - Yes, that Michael Dell. Born in 1965, the founder of Dell, he's one of the richest people in the world. He's a college dropout and took Dell private again in 2014. He got his start in the computer business by creating and selling PC upgrade kits in college.

Sara Blakely - Born in 1971, Blakely is the founder of the wildly popular Spanx undergarments. She got her start selling fax machines door-to-door. She wrote her own patent for Spanx after finding there were no female patent lawyers in the state of Georgia, where she was living at the time.

Steve Easterbrook - Born in 1967, the CEO of McDonald's is a Brit. So long as we don't have to start calling French fries "chips," it's all good. Fitting that the iconic fast-food chain is run by our generation now.

Tom Anderson & Chris DeWolfe - Yep, the founders of MySpace are Xers. Anderson was born in 1970, and DeWolfe in 1966. DeWolfe is now CEO of SGN and Anderson's retired, traveling the world taking photos.

Andrew Wilson - CEO of Electronic Arts, Wilson was born in 1974. He's received a mess of awards for being an influential, hotshot tech CEO.

Let's recap: Tech, video games, fast-food, fashion, and space exploration. Sounds about right for Gen X.

Note: This post was updated to update the name of the company where DeWolf is CEO from Social Gaming Network to SGN.
