الذكاء الاصطناعي في مصر تطور بلا تشريع فمن يتحمل المسؤولية؟ – tahkoom.com
كتبت شروق عارف يشهد العالم تطورا غير مسبوق في التكنولوجيا، حيث أصبح الذكاء الاصطناعي قوة مؤثرة تعيد تشكيل حياتنا وتغيّر قواعد العديد من المجالات. ورغم ما يتيحه هذا التقدم من فرص واسعة، إلا أنه يثير تحديات ومخاوف، خاصة في ظل غياب تشريعات واضحة تنظم استخدامه في مجالات حساسة كالجراحة، والسيارات ذاتية القيادة، والمجال القانوني. هذا الواقع يطرح تساؤلات مهمة، أبرزها: من يتحمل المسؤولية عند حدوث خطأ؟ وتواجه مصر اليوم تحديا في سن قوانين تحمي حقوق الناس وتواكب في الوقت نفسه التقدم التكنولوجي
لا قانون للذكاء الاصطناعي حتى الان
صرح المحامي محمد عاطف بأن الذكاء الاصطناعي لا يخضع حتى الآن لإطار قانوني واضح ومحدد.
وأوضح أنه لا يجوز قانونًا للذكاء الاصطناعي تقديم استشارات قانونية، حيث إن هذه المهام يجب أن تكون من اختصاص محامي مرخص أو جهة قانونية معترف بها، لضمان صحة المعلومات .
وفي ما يتعلق بالمسؤولية الطبية، أشار إلى أن الطبيب هو المسؤول الأول عن الخطأ الطبي، باعتباره صاحب القرار والمتخصص في تقديم الرعاية الصحية، وبالتالي فهو الذي يُسأل قانونًا عند وقوع أي تقصير أو إهمال.
أما في حالات حوادث السير، فقد بين أن السائق هو المسؤول قانونيًا عن أي خطأ يقع أثناء القيادة، لأنه هو المتحكم .
من جانبه، أوضح المحامي الجنائي محمد علي أن الذكاء الاصطناعي لديه القدرة على تقديم استشارات أو خدمات قانونية.
كما أن الذكاء الاصطناعي يمكنه المساعدة في الوصول إلى مواد قانونية أو شرح بعض المفاهيم، لكنه لا يقدم حلولًا قانونية كاملة، ولا يستطيع التعامل مع تفاصيل كل حالة على حدة كما يفعل المحامي البشري.
وأشار إلى أن مصر لا تمتلك حتى الآن قانونًا خاصًا ينظم الذكاء الاصطناعي.
وفي المجال الطبي، أوضح أن القانون المصري لا يميز بوضوح بين الخطأ الناتج عن الإنسان والخطأ الناتج عن الذكاء الاصطناعي.
أما فيما يخص السيارات ذاتية القيادة، فأكد أن مصر لا تملك إطارًا قانونيًا ينظمها حتى الآن.
من جانبه، أكد المحامي المدني رامي أبو رية بأن مصطلح الذكاء الاصطناعي يعد تعبيرا فضفاضا، مما يجعل من السهل القول بأنه لا يوجد قانون محدد ينظم استخدامه.
وأكد على أهمية تحديد نوع المسؤولية القانونية عند مناقشة الأطر التنظيمية للذكاء الاصطناعي، موضحًا أن الحديث هنا ينصب على المسؤولية المدنية، التي تنقسم بدورها إلى نوعين: المسؤولية العقدية والمسؤولية التقصيرية، التي تُعد الأقرب لتطبيقات الذكاء الاصطناعي في الوقت الراهن.
وأوضح أن المسؤولية التقصيرية تقوم على ثلاثة عناصر: الخطأ، والضرر، وعلاقة السببية، وهو ما تنظمه المادة 163 من القانون المدني المصري.
وفيما يتعلق باستخدام الذكاء الاصطناعي في تقديم الاستشارات القانونية، أشار أبو رية إلى أن هذه التقنية يمكنها حاليًا توليد نصوص قانونية تُقدَّم على هيئة استشارات، لكنها لا تستطيع تطبيقها فعليًا.
صرّحت الأستاذة هند توفيق، المحامية المتخصصة بالإستئناف العالي بأن استخدام الذكاء الاصطناعي في مصر يخضع لإطار قانوني واضح، حيث ينظمه قانون حماية البيانات الشخصية الصادر عام 2020، بالإضافة إلى قانون مكافحة جرائم تقنية المعلومات لسنة 2018، ما يضع استخدام هذه التكنولوجيا تحت الرقابة القانونية.
وأوضحت أن الذكاء الاصطناعي يمكن الاستفادة منه في تقديم استشارات وآراء قانونية أو خدمات مساعدة، مؤكدة على استخدامه بشكل فعلي في الأبحاث القانونية وصياغة المذكرات، إلا أن هذه الأدوات لا تحمل طابعًا رسميًا، ويمكن الاعتماد عليها كمصدر تمهيدي أو مساعد، لا أكثر.
وفيما يتعلق بالمسؤولية القانونية في حالة الأخطاء الطبية الناتجة عن استخدام الروبوتات، أكدت أن هناك شقين للمساءلة: جنائي ومدني. ففي الشق الجنائي، يُعد الروبوت بمثابة أداة جراحية، وأي خلل ناتج عنه يؤدي إلى مساءلة الطبيب جنائيًا بتهمة القتل أو الإصابة الخطأ، وفقًا للضرر الواقع. أما في الشق المدني، فالمسؤولية تقع على الطبيب كذلك، باعتبارها مسؤولية تقصيرية، مضيفة أن القانون المدني المصري يتضمن مفهوم “مسؤولية حارس الأشياء”، والتي يمكن تطبيقها على الروبوت باعتباره شيئًا ماديًا، مما يرتب تعويضًا مدنيًا عن الضرر.
وبالنسبة للحوادث الناجمة عن السيارات ذاتية القيادة، أوضحت أن المبدأ نفسه ينطبق؛ حيث يُسأل مالك السيارة مدنيًا، ما لم يثبت أن العطل ناتج عن خلل تقني أو عيب مصنعي، مع تأكيده على اتخاذه الاحتياطات اللازمة. أما من الناحية الجنائية، فلا يوجد حتى الآن نص قانوني واضح يعالج هذه الحالة.
وفي تقييمها للتأثير الاقتصادي للذكاء الاصطناعي، شددت الأستاذة هند على أن هذه التكنولوجيا باتت تمثل خطرًا حقيقيًا على العديد من المهن، خصوصًا تلك التي تعتمد على المهارات الذهنية، مثل مهنة المحاماة والقضاء. لكنها أوضحت أن الوضع في مصر يختلف، إذ لا يمكن الاعتماد كليًا على الذكاء الاصطناعي في تحقيق العدالة، بسبب الطبيعة البشرية لتكوين قناعة القاضي واستنباط القرائن، وهو ما لا تستطيع الخوارزميات محاكاته حتى الآن.
واختتمت حديثها قائلة: “من يعلم؟! ربما نشهد بعد سنوات قليلة طفرة جديدة تجعل الذكاء الاصطناعي قادراً على أداء مهام لم نكن نتخيل أن يفعلها. منذ أربعين عامًا، لو قال لنا أحد أننا سنتحدث اليوم عبر جهاز يسمى الموبايل ونتبادل الرسائل الإلكترونية، لكنا اتهمناه بالجنون”.
لم يعد الذكاء الاصطناعي مجرد فكرة مستقبلية، بل أصبح واقع نعيشه ، ودخل مجالات حساسة تمس حياة الناس بشكل مباشر.
