Artificial intelligence could reshape the education market
Investors, however, appeared to focus more on management's comments regarding a shift to projects with longer-term payoffs. "We're investing proportionally more in teaching better, and we're prioritizing user growth over monetization," CEO Luis von Ahn said in a letter to shareholders.
Yet, although impatient traders are selling Duolingo's stock today, Von Ahn believes the long-term payoffs to both users and shareholders will more than outweigh the near-term costs.
"We're doing this now because we want to keep growing users for a long time, and because of our increasing conviction that AI can fundamentally change what's possible in how we teach," Von Ahn said. "If we develop an app that is more engaging than, and teaches as well as, a personal tutor across multiple subjects, we think we'll become a much bigger business in the long term."
