1960s: "Typewriter aaya, ab likhne ke liye itne log nahi lagenge!" 📝 1990s: "Computer aaya, ab 1000 ki jagah sirf 100 log kaam karenge!" 💻 2020s: "AI aayi, ab 100 ki jagah sirf 10 log kaam karenge!" 🤖 2030s: "AI ne sochna bhi shuru kiya, ab boss bhi ghar baithega!" 🧠 2035s: "AI ne AI bana liya… ab company me sirf WiFi router bacha hai!" 📡 2040s: "WiFi bhi chala gaya… ab bas ek board laga hai – 'Company thi yahan'" 🚪 💡 Moral of the story: Work smart, adapt faster, and never underestimate the WiFi router. 😅 #AI #Automation #FutureOfWork #TechHumor #OfficeJokes #WorkLife #DigitalTransformation #CodingTutorial
