As large language models like OpenAI's GPT-4 become more advanced and able to write, code, and do math with more accuracy and consistency, it won’t be long before AI makes its way into the workplace as a daily-use tool. In fact, OpenAI itself is betting that a vast majority of workers will have at least part of their jobs automated by GPT models. 

In a paper posted to the arXiv preprint server, researchers from OpenAI and the University of Pennsylvania argued that 80 percent of the US workforce could have at least 10 percent of their tasks affected by the introduction of GPTs, the series of popular large language models made by OpenAI. They also found that around 19 percent of workers will see at least 50 percent of their tasks impacted. GPT exposure is greater for higher-income jobs, they wrote in the study, but spans across almost all industries. They argue that GPT models are general-purpose technologies like the steam engine or the printing press.
