abbreviation for “fear of becoming obsolete”: a worried feeling that you may lose your job because your role can be done by AI
Rapid AI advances present an alluring opportunity for businesses to boost productivity and efficiency. But while CEOs battle their FOMO and race to adopt the new technology, their employees are experiencing a different side of the AI revolution — FOBO, the fear of becoming obsolete. It refers to workers’ fears that the speed of artificial-intelligence development is outpacing the reskilling of employees, leaving them redundant in the workplace.

bragawatts noun [plural]
UK /ˈbræg.ə.wɒts/ US /ˈbræg.ə.wɑːts/
the practice of AI companies boasting about very large projects to create excitement and attract investment, even though many of these projects are never completed
Given the practical problems and enormous costs AI data centres face, is the whole movement really one big bubble? One speaker at a recent conference coined the term “bragawatts” to describe how the industry is talking up the scale of proposed AI sites. “The current trajectory is very difficult to believe. There has certainly been a lot of bragging going on. But investment has to deliver a return or the market will correct itself.”
