"Whereas machine intelligence can keep running as long as it has a power supply, a human brain will become fatigued - and you don't have to be a chess grandmaster to understand the feeling. Anyone can end up drained after a long day of work, at school or juggling the countless decisions of daily life. This mental exhaustion can sap motivation, dull focus and erode judgement."
"The efforts are getting a boost in attention and funding in large part because of long COVID, which afflicts roughly 6 in every 100 people after infection with the coronavirus SARS-CoV-2, says Vikram Chib, a biomedical engineer at Johns Hopkins University in Baltimore, Maryland. "The primary symptom of long COVID is fatigue," says Chib. "I think that has opened a lot of people's eyes.""
Machine intelligence can operate continuously with power, while human brains become fatigued, draining motivation, focus and judgement and increasing error risk. Cognitive fatigue affects people in everyday life and can cause deadly medical and traffic mistakes when combined with sleep loss or circadian disruption. Mathias Pessiglione investigated brain fatigue to understand why cognitive systems are prone to fatigue. Researchers have struggled to define, measure and treat cognitive fatigue and are now using experimental approaches and biological markers to probe metabolic causes and consequences. Long COVID, with fatigue as a primary symptom, has driven funding and attention toward this research.
