๐ŸŒ AI in real life

Applied AI โ€” Beginner Level ยท Session 7

Yann Isola

Today we are going on a trip:
a world tour of the places where AI is already working.

Immediate boarding ๐Ÿ—บ

8 stops on the program:

๐Ÿฅ Health ยท ๐Ÿš— Transport ยท ๐ŸŽ“ Education ยท ๐ŸŒพ Agriculture
๐ŸŽฌ Entertainment ยท ๐Ÿ”ฌ Science ยท ๐Ÿ’ฐ Finance ยท ๐ŸŒ Environment

Then:
โš– Limits โ€” what AI can NOT do
๐Ÿš€ Grand finale โ€” you invent YOUR AI application (2 min pitch!)

Before taking offโ€ฆ ๐Ÿค”

Has AI ever done you a favor TODAY?

  • Watched the weather this morning? โœ… AI
  • Follow a route Maps/Waze? โœ… AI
  • Mailbox without spam? โœ… AI
  • A recommended video? โœ… AI
  • Paid by card? โœ… an AI verified the fraud in milliseconds

AI is not โ€œthe futureโ€. It is already everywhere โ€” discreet and invisible.

Stopover 1 ๐Ÿฅ

Health

Eyes that never tire

๐Ÿฅ Assisted diagnosis

A radiologist sees hundreds of images per day. At 300แต‰, the eye gets tired.
An AI analyzes the 300แต‰ with the same attention as the 1สณแต‰.

How did she learn? As for cats (session 2):
hundreds of thousands of x-rays labeled by doctors โ†’ the AI identifies the patterns.

  • Breast cancers on mammograms
  • Melanomas on skin photos
  • Lesions on scanners

โš– The AI flags suspicious areas. The doctor decides. Always.

๐Ÿฅ Discover medications

Finding a medicine = finding a key that fits in a lock ๐Ÿ”‘
Problem: billions of billions of possible keysโ€ฆ

AI simulates millions of molecules โ†’ suggests the best candidates
โ†’ researchers only test the top of the list. Years saved.

โญ The star: AlphaFold โ€” predicted the 3D shape of +200 million proteins,
a 50 year old puzzle. Nobel Prize in Chemistry 2024. โš 

๐Ÿฅ And every day

  • โŒš Connected watches: detection of heart rate anomalies
  • ๐Ÿšจ Patient monitoring in hospital: AI alerts the team before a deterioration
  • ๐Ÿ’Š Medication reminders, fall detection

Quick survey: an AI that reads your radios, would you say yes?
An AI that alone decides on the treatmentโ€ฆ? ๐Ÿ˜ฌ

Stopover 2 ๐Ÿš—

Transport

Who (really) holds the wheel?

๐Ÿš— Autonomous cars: the 5 levels โš | Level | Who drives? | Example |

|---|---|---|
| 1 | Humans, helped with ONE thing | Adaptive regulator |
| 2 | Humans, speed + power steering | Most current โ€œautopilotsโ€ |
| 3 | The car, under conditions | Highway traffic jams, rare models |
| 4 | The car, in a defined area | Robotaxis (some cities) |
| 5 | The car, everywhere, always | Doesn't exist yet! |

Myth to bust: โ€œitโ€™s in 5 yearsโ€โ€ฆ repeated for 10 years. ๐Ÿ˜…

๐Ÿš— Why is level 5 so hard?

Driving is 99% easy.
But the last 1%โ€ฆ

  • ๐Ÿšง Unforeseen work
  • ๐Ÿ‘ฎ An agent who gestures
  • โšฝ A ball that crosses

AI excels at the predictable.
Much less unexpected.

(Remember that โ€” weโ€™ll come back!)

And also: ๐ŸŒ optimized traffic (smart lights, Waze: each phone = a sensor!)
๐Ÿ“ฆ delivery by drones: real but limited โ€” ex. Zipline delivers blood to Rwanda โš 

Stopovers 3 & 4 ๐ŸŽ“๐ŸŒพ

Education and agriculture

๐ŸŽ“ AI at school

  1. Personalized tutoring โ€” a private teacher 24 hours a day, who never gets annoyed and adapts to YOUR level โš 
  2. Automatic correction โ€” the teacher saves time on the repetitive โ†’ more time for the human
  3. Detection of difficulties โ€” the AI detects EARLY when a student is stuck (e.g. fractions) and alerts the teacher

๐Ÿค” Debate: Could an AI replace your favorite teacher?
She explains... but she doesn't motivate, doesn't reassure, doesn't believe in you.

๐ŸŒพ AI in rubber boots

  1. Surveillance drones ๐Ÿ›ธ โ€” photos of the fields โ†’ the AI identifies: here there is a lack of water, there an area is turning yellow
  2. Harvest prediction โ€” weather + soil + satellites โ†’ plan and anticipate
  3. Disease detection ๐Ÿƒ โ€” a photo of a leaf โ†’ diagnosis, even without an agronomist 100 km away

= โ€œprecision agricultureโ€
Less water, less pesticides, more yield. ๐ŸŒ

Stopovers 5 & 6 ๐ŸŽฌ๐Ÿ”ฌ

Entertainment and science

๐ŸŽฌ Couch AI

  1. Recommendations โ€” Netflix, Spotify, TikTok: AI predicts what you will like
    (remember the filter bubbles, session 6!)
  2. Video games ๐ŸŽฎ โ€” animated characters, adaptive difficulty, generated worlds โš 
  3. Cinema ๐ŸŽฅ โ€” rejuvenation of actors, digital crowds, synchronized dubbing

Who has already spent 10 minutes scrolling... what the AI had chosen for them? ๐Ÿ™‹

๐Ÿ”ฌ AI super-assistant for researchers

  1. New molecules & materials โ€” better batteries, more efficient solar panels
  2. Climate ๐ŸŒก โ€” digest mountains of data to refine models and predict extremes
  3. Space ๐Ÿš€ โ€” sorting millions of telescope images (exoplanets found in data already seen by humans!), Mars rovers choosing their path

Human + AI = winning team.
Volunteers classify galaxies โ†’ the AI โ€‹โ€‹learns โ†’ it classifies the remaining millions.

Stopovers 7 & 8 ๐Ÿ’ฐ๐ŸŒ

Finance and the environment

๐Ÿ’ฐ AI and your money

  1. Fraud detection ๐Ÿ›ก โ€” AI knows YOUR habits; weird payment at 3am abroad โ†’ stuck in milliseconds
  2. Algorithmic trading ๐Ÿ“ˆ โ€” a large part of stock market orders go through ultra-fast programs
    โš  setback: โ€œflash crashesโ€ when the algorithms get carried away. Speed โ‰  wisdom.
    3.Banking chatbots ๐Ÿ’ฌ โ€” perfect for simple, frustrating for complicated
    โ†’ the famous โ€œtalk to an advisorโ€ button ๐Ÿ˜‰

๐ŸŒ AI at the bedside of the planet

  1. Deforestation ๐ŸŒณ โ€” satellites + AI = almost real-time alert when trees disappear (before: months of delay!)
  2. Weather โ›… โ€” recent AIs predict 10 days faster โ€” and often better โ€” than classic supercomputers โš 
  3. Energy โšก โ€” cooling of data centers (โˆ’40% at Google โš ), network balancing, integration of solar and wind power

โš– Honesty obliges: the AI itself consumes a lot of energy.
She is part of the solutionโ€ฆ AND part of the problem.

โš– Last stopover

What AI can NOT do

The golden rule ๐Ÿฅ‡

โ€œAI does not replace humans โ€”

she assists him.โ€

The same pattern, everywhere:

Sector AIโ€ฆ The humanโ€ฆ
๐Ÿฅ Health signals decides
๐Ÿš— Transportation assists remain responsible
๐ŸŽ“ Education explains motivates and supports
๐Ÿ’ฐ Finance alert manages the delicate

The 3 red zones of AI ๐Ÿšซ

  1. Context and common sense ๐Ÿงญ
    Irony, customs, innuendoโ€ฆ A recruitment AI reproduced the discrimination of its past data (Amazon case, 2018).

  2. True emotions โค
    She can feign empathy โ€” she doesn't feel anything. Console, announce, negotiate: human.

  3. Pure creativity and the unexpected ๐Ÿ’ก
    It recombines what exists. Invent a new genre, react to something never seen before: it stalls.

The sentence to remember ๐Ÿ“Œ

The AI is unbeatable on repetitive, massive and fast.
Humans remain unbeatable on context, emotion and the unprecedented.
The best teams combine both.

๐ŸŽฎ It's up to you: the impact meter!
For each task, place the cursor between
โ€œAI excelsโ€ โŸท โ€œhumans are irreplaceableโ€

๐Ÿš€ Grand finale

Invent YOUR AI application

2 minute pitch โ€” like a real start-up

๐Ÿ›  The pitch canvas

  1. THE PROBLEM โ€” real, concrete. Who suffers from it?
  2. MY AI SOLUTION โ€” in ONE sentence
  3. DATA โ€” what does my AI learn from? Private life?
  4. WHAT HUMAN KEEP โ€” what decision remains human?
  5. NAME + SLOGAN โ€” that hits! โœจ

โฑ 2 minutes flat At 2:00 sharp: applause, even in full sentence.

The killer question (get ready):

  • โ€œAnd what do humans keep in your system?โ€*

What we remember today ๐ŸŽ’

  • ๐Ÿฅ AI detects cancers, speeds up medications โ€” the doctor decides
  • ๐Ÿš— Levels 1 to 5: level 5 does not exist yet
  • ๐ŸŽ“๐ŸŒพ Personalized tutoring, precision agriculture
  • ๐ŸŽฌ๐Ÿ”ฌ Recommendations, special effects, AlphaFold, space exploration
  • ๐Ÿ’ฐ๐ŸŒ Fraud detected in milliseconds, forests monitored by satellite
  • โš– Golden rule: AI assists, humans decide
  • ๐Ÿšซ Its red zones: context, emotions, pure creativity

Next timeโ€ฆ ๐Ÿงญ

Ethics, privacy and rules of the game

Such a powerful tool deserves safeguards.
We talk about it in session 8!

Challenge of the week: note 3 moments when you come across AI
without having thought about it before this course. ๐Ÿ†

Thank you! ๐ŸŽญ
