We'll All Eat Crickets In 20 Years, Says Cisco's Chambers

Cisco's outgoing executive says clean, cheap insects will be our main source of protein.

Hungry? It's better to get used to eating insects, says the outgoing leader of tech giant Cisco.

"The main source of protein that you will have in your life, certainly in 20 years and maybe in 15 years, will be insects," said John Chambers, speaking at Half Moon Bay at the Techonomy conference. They are "the cleanest way to produce, at least it defies the environment".

In particular, think that eating crickets is the cat's pajamas. This vision aligns well with companies such as Aspire Food Group, which grows crickets for human consumption, and many cultures in Asia, Africa and Latin America. So maybe it's better to adopt an insectivore diet.



Chambers has been the executive director of the Cisco Systems network giant for years, but is now breaking his latest tie as chairman of the company's board. What makes you so expert in food technology? In short, he plans to become more active with startups, and pays close attention to what is happening.
Cricket growth is a high-tech operation, he says, with robots able to help crickets grow 50 percent larger in a third of the time, as usual, he said.
Chambers likes the prospects of Aspire Food Group, based in Austin, Texas, and says that cricket food is now ready. He is also an investor in the food company and mentor of CEO Mohammed Ashour, a spokesman for Aspire confirmed.
However, you will not necessarily know that you are eating small, long-legged arthropods because they can be crushed and added to other foods. He has just made a seven-course dinner at a San Francisco restaurant, Season, with crickets infused with cookies, desserts and even a margarita.
Chambers loves startups, but he worries them in the United States. France and China are doing a better job of encouraging them and making sure they are not isolated from urban coastal pockets.


 "We have become the worst," said Chambers.

And the Silicon Valley seedbed is too complacent, he added.

"When a region is disconnected from technology or from commercial or social changes, it is in danger," said Chambers. "Boston Route 128 was once the world's high-tech center," near MIT and Harvard, home to 2,000 or 3,000 high-tech companies. But the region lost the way to personal computers, software and the Internet and lost its position of influence.

"Silicon Valley has the risk of losing significant market transitions," Chambers said.
