ما بقاش الذكاء الاصطناعي مجرد خيال علمي أو تطور مستنيينه في المستقبل… لأ، ده بقى واقع عايشينه كل يوم، وبيأثر بشكل مباشر على شغلنا، ومهاراتنا، وحتى على الوظايف نفسها. في الفيديو ده، هنتكلم عن إزاي الذكاء الاصطناعي قلب موازين سوق العمل، إيه المهن اللي بدأت تختفي، وإيه اللي طلع جديد، وإزاي نجهز نفسنا للمستقبل اللي بدأ خلاص.
