Science fiction’s wildest dreams are edging into reality. Big Tech is rolling out “universal translators” to millions of users — a gift for globe-trotters, but a headache for DuolingoDUOL

, the quirky app once synonymous with language learning. Now, investors are questioning whether the green owl’s lead is lost in translation.

• DUOL
  has nearly halved from May highs, making it the worst S&P Midcap 400 performer — with analysts warning, “Translation is something AI is very good at … so Duolingo is easily replaceable.”
• Skepticism is growing as AppleAAPL

Still perched at 113x its 12-month earnings — compared to the tech sector’s 43x — Wall Street’s patience is wearing thin as rivals chip away at the language barrier. To branch out, Duolingo is launching music, math, and chess lessons — but lately, the app’s performance isn’t exactly speaking to investors.
