The question of machines can think dates back as far as CS One has to be careful with “big” marketing predictions: “in 5 years machine will be as intelligent as us”.
*
First slide with Simpson – Turing, then The video at the top to explain what it is, finally Blade Runner video to show it came into movies (some students may not get it, state later that he is finding out whether she is an automaton or a person; she doesn’t know but she is realizing. She was a difficult one to catch, required many questions…) *
Very very quick, just state that even in 1700’s someone said that if a Parrot can talk fluidly then we need to accept it is intelligent *
*
So, deciding intelligent does not seem a trivial task, it is very very difficult and cumbersome, muddy, project. We show this video and then jump to the next slide to argue we will rather talk about rationality in AI so to make things easier and more concrete. Still the question of intelligence is interesting and we will come back to it later in the course! *
Rationality as a more approachable notion than “intelligence”. We can formalize “rationality” and build systems for it. But it is just an “approximation”, generaly a “prescriptive” notion of inteligence
Very quick, just state that AI and algorithms are also used in finance
Robots are being used everywhere, from manufacturing to rescue, to space exploration, to agrigulcture
AI can impact everywhere: sports, video games, medicine, personal assistance, cars, art, security, education, markets, etc.
Robots will probably be living with us in important ways, some claim this is dangerous.

— Wominjeka! Welcome! RMIT University acknowledges the Wurundjeri people of the Kulin Nations as the traditional owners of the land on which the University stands. RMIT University respectfully recognises Elders both past and present.
Acknowledgement I acknowledge the Traditional Owners (Woiwurrung and Boonwurrung form the Kulin nations) of the land on which we will conduct the whole Artificial Intelligence 2021 course during this semester. I, and invite you all to, pay our respects to their Elders, past and present, and the first people of other communities who may be here today. And to be aware of the challenges and injustices that unfortunately continue up to our times . I recognise their continuing connection to land, waters and culture.

Wh ere is AI?
The age of Intelligent Systems “Beyond Voice Recognition: It’s The Age Of Intelligent Systems” Forbes’ article by CTO of NUANCE: http://www.forbes.com/sites/ciocentral/2013/01/11/beyond-voice-recognition-its-the-age-of-intelligent-systems/ January 2013
So, what is “AI”? “Artificial intelligence is that activity devoted to making machines intelligent, and intelligence is that quality that enables an entity to function appropriately and with foresight in its environment.” — Nils J. Nilsson
What is Intelligence? {E4F0F444-259E-4AF3-AB86-9647F25909A9} talk “Hello! How are you today. Could I please have a coffee?” hear Interpret “er… so.. um… as I was saying, what? No! Coffee please!” read Interpret “Time flies like an arrow. Fruit flies like a banana.” think “Low on fuel, it’s getting dark, no clue where I am … Hmmmm….” act Pick things up, move them, walk, build things, … see Distinguish moving objects from static ones, colours, textures, … adapt This isn’t working, so let’s try something else … paint Make judgements about what is pleasing and what is not

Deciding Intelligence: Difficult task!
Rationality Turing test: Behaves like a human, but thinks like a human? Doesn’t help much on how to build an intelligent system Rationality as an alternative: Precise mathematical notion of what it means to do the right thing in any particular circumstance. Humans not always rational ! style.visibility style.visibility
So, what is AI? Thus we try to construct systems whose computation achieves or approximates the desired notion of rationality . Hence AI is part of Computer Science. Other areas interested in the study of intelligence lie in other areas of study, e.g., cognitive science, psychology, philosophy, neuroscience: central focus tends to be different. How to achieve intelligent behavior through computational means. style.visibility
