Re-engineering Iraq

U.S. and Iraqi officials have spent billions on restoring Iraq’s electrical system. So why is Baghdad getting just 6 hours of electricity a day?

For more than 25 years, Rory Cooper has been developing technology to improve the lives of people with disabilities.

Cooper began his work after a spinal cord injury in 1980 left him paralyzed from the waist down. First he modified the back brace he was required to wear. He then turned to building a better wheelchair and came up with an electric-powered version that helped its user stand up. He eventually discovered biomedical engineering and was inspired to focus his career on developing assistive technology. His inventions have helped countless wheelchair users get around with more ease and comfort.

The next wave of Moore’s Law will rely on a developing concept called system technology co-optimization, Ann B. Kelleher, general manager of technology development at Intel told IEEE Spectrum in an interview ahead of her plenary talk at the 2022 IEEE Electron Device Meeting.

“Moore’s Law is about increasing the integration of functions,” says Kelleher. “As we look forward into the next 10 to 20 years, there’s a pipeline full of innovation” that will continue the cadence of improved products every two years. That path includes the usual continued improvements in semiconductor processes and design, but system technology co-optimization (STCO) will make the biggest difference.
