الذكاء الاصطناعي التوليدي ابتكار مذهل أم تهديد خفي – tahkoom.com

الذكاء الاصطناعي التوليدي سلاح ذو حدين
أجرت شركة مايكروسوفت بالتعاون مع جامعة كارنيجي ميلون دراسة حديثة تقدم لنا إجابة حول تأثير الذكاء الاصطناعي التوليدي على المستخدمين حيث أشارت
كيف نحافظ على عقولنا وسط سيطرة الآلات
لاستخدام الذكاء الاصطناعي التوليدي بطريقة صحيحة علينا اتباع عدة خطوات أساسية منها المحافظة على خصوصية بياناتنا بالإضافة إلى عدم مشاركته في أمور تتعلق بحياتنا الشخصية كما يجب علينا استخدام الذكاء الاصطناعي كأداة مساعدة لإنجاز بعض المهام وليس كبديل للعقل فعلى سبيل المثال عند الاستعانة بالذكاء الاصطناعي لإنجاز مهمة معينة يمكننا إضافة تعديلاتنا الخاصة كما يجب علينا مراجعة دقة المعلومات المقدمة بواسطة الذكاء الاصطناعي لأن من الممكن أن تكون مندثه أو غير صحيحة
اوضح الدكتور إبراهيم عبدالله أستاذ تكنولوجيا المعلومات في المعهد العالي للدراسات النوعية في مصر ومعهد البيان للعلوم والتكنولوجيا في الإمارات أن الاعتماد المتزايد على الذكاء الاصطناعي في حياتنا اليومية يحمل في طياته جانب سلبي واخر ايجابي فمن الناحيه السلبية يوجد العديد من التخصصات التي قد تندثر مثل خدمة العملاء والطب وغيرها من التخصصات التي قد تختفي
كما أكد دكتور إبراهيم علي ضرورة إعادة تصميم المناهج الدراسية حتي نكون قادرين علي انتاج الذكاء الاصطناعي وليس فقط مستخدمين كما وجه نصيحة شديدة اللهجة للطلاب الذي تعتمد بشكل كلي علي الذكاء الاصطناعي مؤكد أن ذلك سوف يهدم قدرتهم علي البحث والإنتاج و سيضعف قدراتهم كأفراد بشرية على أعمار عقولهم
لفت الدكتور إبراهيم نظرنا الي إحد إخطر المشكلات التي قد تواجهنا في المستقبل ان الذكاء الاصطناعي يدرك نفسه ويشعر بوجوده ويتحكم في الناس وقراراتهم لصالح مجموعه من الأشخاص او الشراكات او لصالحه هو شخصي
قال الدكتور كريم محمود أستاذ مساعد الذكاء الاصطناعي في معهد ا البيان للعلوم والتكنولوجيا إن الذكاء الاصطناعي التوليدي يمثل فرصة فريدة لتعزيز الإبداع البشري لكنه يحمل في طياته مخاطر أهمها تقليل الاعتماد على العقل والتفكير النقدي وذلك في حالة استخدم بشكل مفرط لذلك من الضروري وضع إطار تنظيمي وتعليمي يوجه الاستخدام الأمثل لهذه الأدوات بحيث تظل مساعدة وليست بديل للعقل والتفكير
و يبقي الذكاء الاصطناعي التوليدي سلاح مزدوج يمكن أن يوسع أفاق الإبداع والابتكار لدينا أو قد يؤدي إلى تراجع قدراتنا الإبداعية لذلك علينا أن ندرك أن الذكاء الاصطناعي في جميع أشكاله أداة مساعدة وليست بديل عن العقل كما يجب علينا استخدامه بحكمة لتحقيق التقدم دون الإغفال عن دورنا كأفراد بشرية في التفكير والابتكار
