More than three-quarters of The Information readers say they have used artificial intelligence tools in place of traditional search engines such as Google, and nearly the same proportion say they use chatbots to help them at work. Readers also are more optimistic about the technology sector after a summer dip, according to The Information’s September survey. Respondents who said they expect conditions for the technology sector to improve over the next six months outnumbered those who think conditions will worsen by more than 5 to 1. In all, 1,088 readers responded to the survey from Sept. 12 until Tuesday.
