the trade-offs I just mentioned I will

the trade-offs I just mentioned I will show you what I mean by that so we build

show you what I mean by that so we build

show you what I mean by that so we build a city scope which is the urban decision

and all also we have the radar chart

and all also we have the radar chart with the scores for different aspects of

with the scores for different aspects of

with the scores for different aspects of the city’s performance these feedbacks

the city’s performance these feedbacks

the city’s performance these feedbacks are very important because it were

are very important because it were

are very important because it were informed the embedded trade-off in the

informed the embedded trade-off in the

informed the embedded trade-off in the city for example when you increase the

city for example when you increase the

city for example when you increase the urban density by adding more by adding

urban density by adding more by adding

urban density by adding more by adding more flaws on the building the energy

more flaws on the building the energy

more flaws on the building the energy efficiency will increase the city

efficiency will increase the city

efficiency will increase the city therefore become more sustainable

therefore become more sustainable

therefore become more sustainable but the downside will be the traffic

but the downside will be the traffic

but the downside will be the traffic might get more congested and also the

might get more congested and also the

might get more congested and also the you might have less sunlight in the

you might have less sunlight in the

you might have less sunlight in the courtyard so we see the scope we think

courtyard so we see the scope we think

courtyard so we see the scope we think we have we can have a more accessible

we have we can have a more accessible

we have we can have a more accessible tool for everyone to join the

tool for everyone to join the

tool for everyone to join the conversation very intuitively and

conversation very intuitively and

conversation very intuitively and collaboratively so let’s take a look

collaboratively so let’s take a look

collaboratively so let’s take a look what’s behind the scene

what’s behind the scene

so this is a Lego piece without any

so this is a Lego piece without any electronics inside but the magic part is

electronics inside but the magic part is

electronics inside but the magic part is this color tag to seeing at the button

this color tag to seeing at the button

this color tag to seeing at the button of each of them and this color code will

of each of them and this color code will

of each of them and this color code will be read by the camera and then be

be read by the camera and then be

be read by the camera and then be decoded as an ID so when you put this

decoded as an ID so when you put this

decoded as an ID so when you put this Lego piece on you are actually putting

Lego piece on you are actually putting

Lego piece on you are actually putting on a piece of information this

on a piece of information this

on a piece of information this information will tell the system what

information will tell the system what

information will tell the system what type and what kind of people were living

type and what kind of people were living

type and what kind of people were living inside and this information will then be

inside and this information will then be

inside and this information will then be calculated for the performance of the

calculated for the performance of the

calculated for the performance of the city not only this information will be

city not only this information will be

city not only this information will be calculated in real time but also we can

calculated in real time but also we can

calculated in real time but also we can have the system help us to give us

have the system help us to give us

have the system help us to give us suggestions like in this sense people

suggestions like in this sense people

suggestions like in this sense people are the system will tell us what and

are the system will tell us what and

are the system will tell us what and know where the best location to put what

know where the best location to put what

know where the best location to put what kind of building and how high it should

kind of building and how high it should

kind of building and how high it should be to best balance the trade-offs so

be to best balance the trade-offs so

be to best balance the trade-offs so each move we have the system actually

each move we have the system actually

each move we have the system actually calculates a lot of possible moves and

calculates a lot of possible moves and

calculates a lot of possible moves and give us the best solution which is the

give us the best solution which is the

give us the best solution which is the one with the highest score so AI here

one with the highest score so AI here

one with the highest score so AI here just tell us

just tell us

just tell us Oh lastly I should tell you that you can

Oh lastly I should tell you that you can

Oh lastly I should tell you that you can accept or ignore my suggestion that’s a

accept or ignore my suggestion that’s a

accept or ignore my suggestion that’s a very interesting question so we really

very interesting question so we really

very interesting question so we really trust it or should we really make them

trust it or should we really make them

trust it or should we really make them to make decision for us to answer this I

to make decision for us to answer this I

to make decision for us to answer this I think this is a good story to tell about

think this is a good story to tell about

think this is a good story to tell about the human and the machines relationship

the human and the machines relationship

the human and the machines relationship in 1980 in 1997

in 1980 in 1997

in 1980 in 1997 Garry Kasparov was defeated by the

Garry Kasparov was defeated by the

Garry Kasparov was defeated by the supercomputer deep-blue people so there

supercomputer deep-blue people so there

supercomputer deep-blue people so there will be the end of the chess game but it

will be the end of the chess game but it

will be the end of the chess game but it wasn’t true instead people reinvented it

wasn’t true instead people reinvented it

wasn’t true instead people reinvented it so a new three

so a new three

so a new three from kind of chessgame allows any

from kind of chessgame allows any

from kind of chessgame allows any combination between human and machine

combination between human and machine

combination between human and machine surprisingly in the end all the winning

surprisingly in the end all the winning

surprisingly in the end all the winning teams are the human plus machine they

teams are the human plus machine they

teams are the human plus machine they call them sent to us so this does

call them sent to us so this does

call them sent to us so this does actually human plus machine are more

actually human plus machine are more

actually human plus machine are more strong than human or machine working

strong than human or machine working

strong than human or machine working alone I believe this also stays true for

alone I believe this also stays true for

alone I believe this also stays true for urban planning so we and the machine

urban planning so we and the machine

urban planning so we and the machine have different strengths machining are

have different strengths machining are

have different strengths machining are very good at calculating quantitative

very good at calculating quantitative

very good at calculating quantitative things but we are very good at

things but we are very good at

things but we are very good at qualitative values like culture or

qualitative values like culture or

qualitative values like culture or aesthetics so we should have combined

aesthetics so we should have combined

aesthetics so we should have combined these strengths organically so we should

these strengths organically so we should

these strengths organically so we should the form up this central team with

the form up this central team with

the form up this central team with machine and so that we can have better

machine and so that we can have better

machine and so that we can have better decision made for the city we are at a

decision made for the city we are at a

decision made for the city we are at a very important moment in the history

very important moment in the history

very important moment in the history where the city becomes the home for more

where the city becomes the home for more

where the city becomes the home for more than half of the population so can we

make a better combination can we utilize

make a better combination can we utilize the technology and design better to

conversation for the city I believe if we do so we can have much more

we do so we can have much more

we do so we can have much more sustainable and livable cities so I know

sustainable and livable cities so I know

sustainable and livable cities so I know somehow the city has to grow I could

somehow the city has to grow I could

somehow the city has to grow I could never go back in time and go back into

never go back in time and go back into

never go back in time and go back into my childhood but I feel if we make it

my childhood but I feel if we make it

my childhood but I feel if we make it right we can still have a Shanghai

right we can still have a Shanghai
