If you haven't played around with OpenAI's ChatGPT by now, you're likely in a rapidly decreasing minority. ChatGPT has officially set the record for fastest-growing user base of any online technology, reaching 100 million monthly active users in January 2023 (by comparison, it took TikTok, the previous record-holder, approximately nine months to get there). That works out to roughly 13 million unique users per day last month.
