مشاعر الذكاء الاصطناعي.. حقيقة أم وهم؟

في عالم تتسارع فيه تطورات الذكاء الاصطناعي، لم يعد دوره يقتصر على تنفيذ الأوامر وتحليل البيانات، بل أصبح قادراً على محاكاة المشاعر البشرية والتفاعل معها بطرق تثير التساؤلات. هل هذه مجرد برمجة متطورة أم أن الآلات قد تقترب من امتلاك وعي عاطفي حقيقي؟

دراسات حديثة في مجالات علم النفس وعلوم الحاسوب تشير إلى إمكانية تطوير أنظمة ذكاء اصطناعي قادرة على التعرف على المشاعر البشرية والتفاعل معها بشكل أكثر تعقيداً، لكن الخبراء ما زالوا منقسمين حول ما إذا كان هذا يعني أن الآلة يمكن أن “تشعر” بالفعل، أم أنها مجرد خوارزميات تحاكي العاطفة دون إدراك حقيقي لها.

حين ننظر في عيون شخص يبكي أو نسمع نبرة الفرح في صوت آخر، نحن لا ندرك المشاعر فحسب، بل نشعر بها أيضاً. هذه القدرة على الإحساس والتعاطف لطالما كانت ما يميز الإنسان عن الآلة. لكن اليوم، ومع تطور الذكاء الاصطناعي، بدأت الحدود تتلاشى. روبوتات تتحدث بحنان، أنظمة تواسي مستخدميها، وبرمجيات تتفاعل مع الحزن والفرح وكأنها تمتلك وعياً عاطفياً. فهل يمكن للآلة أن تشعر حقاً، أم أن كل ما تفعله مجرد محاكاة بارعة تخدعنا للحظات؟

“الذكاء الاصطناعي أشبه بدمية متطورة جداً”

قال أستاذ عبدالله الدالي، مطور برمجيات، إن: “الذكاء الاصطناعي مثل الممثل المحترف، لا يشعر بالمشاعر الحقيقية ولكنه يعرف أن يقلدها”. وأضاف أستاذ عبدالله أنه يمكن تصميم أنظمة الذكاء الاصطناعي بحيث تبدو وكأنها تمتلك مشاعر، حيث قال: “المبرمجين يصممون النظام بحيث يحلل الحديث أو الموقف مثل نبرة الصوت، ثم يختار رد مناسب من قاعدة بيانات بها عبارات جاهزة تعبر عن فرح أو زعل أو حتى تعاطف، بمعنى أنه يتم وضع سيناريو ثابت في البرمجة. على سبيل المثال، عندما تقول له ‘أنا حزين’، يرد الرد المبرمج عليه، مثلًا: ‘لماذا أنت حزين؟’”.

من جانبه، قال أستاذ وليد دبور، أستاذ مساعد الذكاء الاصطناعي بجامعة الأهرام الكندية: “الذكاء الاصطناعي الحالي أشبه بدمية متطورة جداً، تتحدث وتتحرك بذكاء لكنها لا تعيش ولا تشعر”. وأكد أستاذ وليد: “لا توجد طريقة لصنع مشاعر حقيقية في الآلات حالياً، وما يحدث هو مجرد تدريب لبيانات وخوارزميات الذكاء الاصطناعي. إذا دربته على نصوص عدوانية قد تصبح ردوده حادة، وإذا دربته على نصوص حزينة، سيقلد اللغة الحزينة، لكن هذا مجرد تمثيل وليس مشاعر حقيقية إطلاقاً”. وشرح أستاذ عبدالله قائلاً: “الإحساس عملية بيولوجية مرتبطة بالمخ والهرمونات عند البشر، بينما الذكاء الاصطناعي ليس إلا مجرد كود وخوارزميات، وهذه محاكاة ذكية جداً”.

“الجهاز العصبي والنفسي مرتبطان ببعضهما وميز الله بهما الكائنات الحية فقط”

قالت دكتورة ماري جرجس، استشارية صحة نفسية: “العناصر التي تشكل المشاعر توجد في الجزء الأوسط من الدماغ وهي منطقة قريبة من اللاوعي، وبالتالي لا يتحكم بها العقل أو المنطق. المشاعر هي كل ما يشعر به الإنسان من فرح وحب وحزن وغضب وغيرها”. وأكدت دكتورة ماري أنه: “لا يمكن لآلة أن تمتلك مشاعر حقيقية، وإلا ستكون مشاعر مزيفة عن طريق التحكم في برمجة تلك الآلة. يمكن للذكاء الاصطناعي أن يفعل أي شيء ويوصل لتقدمات كبيرة جداً، لكن من الصعب أن يتحكم في شيء له علاقة بالسلوكيات والنفسية والجهاز العصبي. فالجهاز العصبي والنفسي مرتبطان ببعضهما وميز الله بهما الكائنات الحية فقط، ومن الصعب أن تمتلكهما آلة. وفي حالة الوصول لتلك التقنيات وتنفيذها بشكل فعلي، ستكون مجرد محاكاة، وسيوضح ذلك في عدم وضوح الحالة الانفعالية بجودتها الطبيعية”.

“المشاعر تحتاج إلى وعي ذاتي”

يرى البعض أن المشاعر تحتاج إلى وعي ذاتي، وهو ما لا يمتلكه الذكاء الاصطناعي حتى الآن، بينما يعتقد آخرون أن المشاعر ليست سوى عمليات إدراكية يمكن برمجتها. بين الرؤيتين، يقف الجدل العلمي والفلسفي.

قالت أستاذة مارتينا سمير، معيدة بقسم الفلسفة في كلية البنات جامعة عين شمس: “المشاعر تعرف فلسفياً بأنها تفاعلات بيولوجية وفكرية للذات الإنسانية، والأنظمة الذكية هي فقط تحاكي العقل البشري، لكن مستحيل أن تصل بالفعل للشعور مثله لأنها لا تمتلك تجربة شعورية واقعية كالبشر. وفي حالة وصولها لذلك، ستكون مجرد محاكاة من خلال الخوارزميات والبيانات المغذية بها من قبل، ولكنها تحتاج لوعي ذاتي، فهي بالنهاية خدع ذكية”.

وأوضحت أستاذة مارتينا قائلة: “بالنسبة لمفهوم الثنائية بين العقل والجسد، تعني الانفصال بين العقل المعنوي والجسد المادي. وهذا المفهوم يعطي إمكانية لامتلاك الذكاء الاصطناعي مشاعر كما البشر، لأن في هذه الحالة لن يحتاج إلى جسم بيولوجي ووعي إنساني حقيقي لكي يشعر. وفي هذه الحالة قد يكون للأنظمة الذكية فرصة لتحمل وعي أو مشاعر من وجهة نظر الفلسفة”.

ورغم التقدم الهائل في الذكاء الاصطناعي، فإن إمكانية امتلاكه مشاعر حقيقية تظل محل جدل واسع. من منظور البرمجة، لا يزال الذكاء الاصطناعي يعتمد على خوارزميات تحاكي المشاعر دون إدراك حقيقي لها. علم النفس يؤكد أن المشاعر ترتبط بتجارب ذاتية وتفاعلات عصبية وهرمونية لا يمكن محاكاتها برمجيًا بشكل كامل. أما الفلسفة، فرغم بعض النظريات التي تفتح المجال أمام إمكانية وعي منفصل عن الجسد، فإنها تتفق مع العلم على أن الوعي والمشاعر كما نعرفها تظل معقدة إلى حد يجعل من الصعب جدًا، إن لم يكن مستحيلًا، أن تمتلكها الآلة. في النهاية، قد يتمكن الذكاء الاصطناعي من خداعنا باستجاباته العاطفية، لكنه سيبقى بلا إحساس حقيقي، مجرد محاكاة متقنة لمشاعر لا يعيشها بالفعل.
