I mentioned recently that I had couldn’t remember any technology being adopted into widespread commercial and public use as fast as the large language models. Here is some empirical confirmation of my impression, from Reuters:

ChatGPT, the popular chatbot from OpenAI, is estimated to have reached 100 million monthly active users in January, just two months after launch, making it the fastest-growing consumer application in history, according to a UBS study on Wednesday.

The report, citing data from analytics firm Similarweb, said an average of about 13 million unique visitors had used ChatGPT per day in January, more than double the levels of December.

“In 20 years following the internet space, we cannot recall a faster ramp in a consumer internet app,” UBS analysts wrote in the note.

Websites and apps are not exactly technologies, and the large learning models are more than just websites or apps. What about cell phones themselves, or radio, or electricity, or toothpaste, or the plough, or the wheel, or fire? I think the adoption of all these critical technologies probably had a half life measured in years at least, probably decades or even centuries the further back you go. I’m sure there are many scholarly studies out there.
