+In 1956, the summer workshop of Darmouth was held with prestigious participants (Minsky, Shannon, McCarthy, etc.). 
+This event marked the starting point of Artificial Intelligence as a field on its own. 
+The hopes were high: beating a chess champion, prove math theorems, replace human’s works. Following this meeting, Rosenblatt created the perceptron in 1958, a very simplified model of a biological neuron that aimed to classify images. Yes, “artificial neural networks” and “computer vision” aren’t new.

+
+Ng is an adjunct professor at Stanford University (formerly associate professor and Director of its Stanford AI Lab or SAIL). Ng has also made substantial contributions to the field of online education as the co-founder of both Coursera and deeplearning.ai
+
+ Ng believes that AI technology will improve the lives of people, not that it is an anathema that will "enslave" the human race.[3] Ng believes the potential benefits of AI outweigh the threats, which he believes are exaggerated.[63] He has stated that
+
+    Worrying about AI evil superintelligence today is like worrying about overpopulation on the planet Mars. We haven't even landed on the planet yet![63]
+
+A real threat is regarding the future of work: "Rather than being distracted by evil killer robots, the challenge to labour caused by these machines is a conversation that academia and industry and government should have."[64] A particular goal of Ng's work is to "democratize" AI learning so that people can learn more about it and understand its benefits. Ng's stance on AI is shared by Mark Zuckerberg, but opposed by Elon Musk.[64]
+
+In 2017, Ng said he supported basic income to allow the unemployed to study AI so that they can re-enter the workforce. He has stated that he enjoyed Erik Brynjolfsson and Andrew McAfee's "The Second Machine Age" which discusses issues such as AI displacement of jobs.[65]

+## Lvl 2.1: Bonus - Testez OpenAI Codex
+
+- Créez votre compte sur OpenAI
+- Testez OpenAI Codex : écrivez la signature et la docstring d'une fonction qui remplit un besoin simple (valider qu'un username correspond à X, valider qu'un nombre a telle propriété, etc), puis laissez le modèle générer son code.
+- Partagez le code généré, et en quelques mots votre opinion : quelles forces ? quelles faiblesses ? quels avantages ou risques à s'en servir au boulot ?
+

+
+### Lvl 3: Jouer avec des Image Models
+
+- Ouvrez "ThisPersonDoesNotExist" et dites en quelques mots votre impression sur la qualité des images générées.
+- Ouvrez "ThisXDoesNotExist", choisissez un autre modèle, et commentez sa qualité.
+
+--- 
+
+### Lvl3 Bonus: Votre propre génération d'image
+
+Utilisez MidJourney, CrAIyon (Dall-E Mini), StableDiffusion ou DeepDreamGenerator pour créer une image basée sur un prompt textuel ou sur du style transfer.
+
+Incluez votre résultat préféré dans ce rendu et commentez :
+- Où-est-ce que le modèle excelle ?
+- Où-est-ce que le modèle échoue ? 
+- Avez vous essayé un autre sujet d'abord, que le modèle a échoué à réaliser ?
