1
you've highly lauded Elon and XAI's accomplishment in Memphis in building Colossus supercomputer,
2
probably in record time in just four months.
3
It's now at 200,000 GPUs and growing very quickly.
4
Is there something that you could speak to,
5
understand about his approach that's instructive broadly to all the data center creators that enable that kind of accomplishment?
6
his approach to engineering, his approach to the whole management of construction, everything.
7
First of all, Elon is deep in so many different topics,
8
yet he's also a really good systems thinker.
9
And so he's able to think through multiple disciplines.
10
And he obviously pushes things,
11
questions everything, whether number one, is it necessary?
12
number two does it have to be done this way
13
and in other words you know does it have does it have to take this long
14
and and so
15
so he he has he has the he has the ability
16
uh to question everything uh to the point where everything is
17
down to its minimal amount that's necessary you can't take anything else out
18
and and yet yet the the the the the necessary um capabilities of the product retains you know
19
and so he's he is as minimalist as you could possibly imagine
20
and he does it at a system system scale um i i also love the fact
21
that he he is um he is represented he he is he is present at the point of action.
22
You know, he'll just go there.
23
If there's a problem, he'll just go there and show me the problem.
24
You know, when you do all of this in combination,
25
you overcome a lot of previous,
26
this is just the way we do it.
27
You know, I'm waiting for them.
28
You know, I mean, it's just,
29
everybody has a lot of excuses.
30
And so, and then the last thing is,
31
When you act personally with so much urgency,
32
it causes everybody else to act with urgency.
33
Every supplier has a lot of customers going on.
34
Every supplier has a lot of projects going on.
35
He makes it his business that he's the top priority of everybody else's projects.
36
He does that by demonstrating it.
37
I've been in a bunch of those meetings.
38
It's fun to watch because really not enough people ask the question like,
39
okay, so can this be done a lot faster and how?
40
Why does it have to take this long?
41
Yeah, right.
42
And then that becomes an engineering question often.
43
And yes, I think when you get the ground truth of actually,
44
I remember one of the times I was hanging out with him,
45
he literally is going through the entire process of how to plug in cables into a rack.
46
He's working with an engineer on the ground that's doing that task,
47
and he's just trying to understand what does that process look like so it can be less error-prone.
48
And just building up that intuition from every single task involved in putting together the data center,
49
you start to immediately get a sense at the detailed scale and at the broad system scale of where the inefficiencies are.
50
And so you can make it more and more and more efficient.
51
Plus, you have the big hammer of being able to say,
52
let's do it totally different and remove all possible blockers.
53
That's right.
54
is there parallels in the nvidia extreme systems code design approach that you see in the way Elon approaches systems engineering?
55
Well, first of all, co-design is an ultimate systems engineering problem.
56
And so we approach the work that we do from that principle.
57
The other thing that we do,
58
and this is a philosophy that,
59
a thought, a state of mind,
60
I guess, a method that I started 30 years ago,
61
and it's called the speed of light.
62
A speed of light is not just about the speed.
63
A speed of light is my shorthand for what's the limit of what physics can do.
64
And so everything that we do is compared against the speed of light.
65
Memory speed, math speed, power,
66
cost, time, effort, number of people, manufacturing cycle time.
67
and when you think about latency versus throughput,
68
when you think about cost versus throughput,
69
cost versus capacity, all of these things,
70
you test against the speed of light to achieve all of these different constraints separately.
71
And then when you consider it together,
72
you know you have to make compromises because a system that achieves extremely low latency
73
versus a system that achieves very high throughput are architected fundamentally differently.
74
But you want to know what's the speed of light of a system that achieves high throughput?
75
What's the speed of light of a system that achieves low latency?
76
And then when you think about the total system, you could make trade-offs.
77
And so I force everybody to think about what's the first principles,
78
the limits the physical limits um for everything before we you know before we uh do anything
79
and and we test everything against that and
80
so that's a good frame of mind i don't love the other methods which is continuous improvement
81
the problem with continuous improvement it first of all you should
82
engineer something from first principles at the speed you know with speed of light thinking limited only by physical limits
83
and and physics limits and um after
84
that of course you would improve it over time um
85
but i don't like going into a problem
86
and somebody says hey you know it takes 74 days to do this today right now
87
and we can do it for you in 72 days you know i'd rather strip it all back to zero
88
and say first of all explain to me why it's 74 days in the first place
89
and let's think about what's possible today.
90
And if I were to build it completely from scratch,
91
how long would it take?
92
Oftentimes you'd be surprised and might come to six days.
93
Now the rest of the six days to 74
94
could be very well-reasoned and compromises and cost reductions and all kinds of different things,
95
but at least you know what they are.
96
And then now that you know that six days is possible,
97
Then the conversation from 74 to 6 Surprisingly much more effective

Uitspraak om op te letten
De spreker gebruikt 10 samentrekkingen en verkorte vormen, zoals don't, he'll, can't. Spreek ze kort uit, zoals je ze hoort.
- De “th”-klanken: throughput /ˈθɹuː.pʊt/, thinker /ˈθɪŋ.kɚ/
- De klanken “sh” en “zh”: accomplishment /əˈkɑm.plɪʃ.mənt/, shorthand /ˈʃɔɹthænd/, intuition /ˌɪn.tjuːˈɪʃ.ən/
- Lange woorden — let op de klemtoon: accomplishment /əˈkɑm.plɪʃ.mənt/, minimalist /ˈmɪn.ə.məl.ɪst/, intuition /ˌɪn.tjuːˈɪʃ.ən/, capability /ˌkeɪ.pəˈbɪl.ɪ.ti/
Klanken die Nederlandstaligen lastig vinden:
- Stemhebbende eindmedeklinker — /b/, /d/, /g/, /z/, /v/ niet verscherpen: instructive /ɪnˈstɹʌktɪv/, oftentimes /ˈɔf.ənˌtaɪmz/, shorthand /ˈʃɔɹthænd/
- /æ/ — opener dan de Nederlandse “e”: shorthand /ˈʃɔɹthænd/, rack /ɹæk/
Zo oefen je met deze video
- Luister de hele video één keer zonder te spreken en noteer de woorden die je niet kent.
- Begin op 0,75× snelheid, spreek zin voor zin na en ga terug naar normale snelheid zodra het makkelijk gaat.
- Neem jezelf op en vergelijk met het origineel; let daarbij op woorden als latency, accomplishment, supplier.
Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
