1
You are reinforcing the ideas of preferences that some people are more valuable than others.
2
Hey.
3
Hey.
4
How are you?
5
Yeah, very good.
6
25-year-old Kyan Sadehi runs a tech startup called Nucleus Genomics.
7
His company uses AI algorithms to analyze the DNA of his customers' future children like never before.
8
These are nitrogen tanks, I think.
9
Yes.
10
How many embryos do you reckon there are in here?
11
Like millions?
12
If all the samples here were embryos,
13
yes, there would be millions, yes.
14
Millions of potential new humans?
15
Yeah.
16
Kian uses AI to map each embryo's DNA,
17
comparing it against huge DNA databases to try to predict a baby's future risk of disease.
18
Some diseases can be predicted with certainty.
19
For others, he can say how people with similar DNA turned out.
20
When I talk to a couple,
21
they say, my grandfather had Alzheimer's.
22
I want to do anything I can to make sure my son doesn't have Alzheimer's.
23
And then I think, well,
24
genetics obviously can help with that.
25
And so I think more people are going to use IVF,
26
and they're going to be using genetic optimization technology to basically pick their child.
27
Figuring out whether a baby will develop Alzheimer's later in life is a best guess,
28
not a diagnosis.
29
But the company goes further,
30
helping parents choose an embryo based on eye color, height or even IQ.
31
Kian had already raised $32 million from investors.
32
He just launched a glossy new ad campaign.
33
I think it is.
34
OK, let's go.
35
Nucleus Embryo is for couples doing IVF to uncover the full genetic profile of each embryo in one intuitive platform.
36
Every parent deserves the power to decide what possibility feels right for their family.
37
Some people don't think you should have this choice,
38
but it's not their choice to make.
39
It's yours.
40
You're not afraid of controversy, are you?
41
No, no, no, no. It's not about...
42
It's...
43
You know, if you were doing IVF and you had five embryos,
44
would you want to pick your future baby randomly?
45
Or would you ask the doctor for more information on each,
46
especially if you have a family history of Alzheimer's, of cancer?
47
It's my right to know this information.
48
It's my choice to say I want a baby at lower disease risk,
49
I want a baby that's slightly taller,
50
or even with a specific eye colour,
51
etc. It's their right, it's their choice.
52
I think what you're doing,
53
where people have genetic predispositions for particular diseases,
54
especially when they're preventable or treatable, I think it's amazing.
55
What I don't understand is why you would include to something like IQ and eye color.
56
Because it's so controversial.
57
And it's like, it's a little bit eugenics-y, you know?
58
You are implicitly saying that taller is better.
59
You are reinforcing the ideas of preferences that some people are more valuable than others.
60
No, not at all.
61
I think parents have the right to choose across their embryos,
62
right, if they want a baby with a lower disease risk,
63
for example, or if they want a baby that's shorter or taller.
64
That's absolutely their right to choose.
65
This is designer babies, though.
66
I mean, bluntly, this is designer babies.
67
No, no, it's not designer babies at all, actually.
68
How is it not designer babies?
69
It's not designer babies at all.
70
If a parent wants to give their child the best starting life,
71
that is like a parent doing the most basic,
72
in my mind, and human thing.
73
If a parent...
74
The moment a child is born,
75
they will run multiple tests on a baby to make sure the baby's healthy.
76
They'll give it vaccines, for example,
77
to make sure they don't get diseases.
78
This is just another tool in the toolkit that helps parents do that.
79
But there was something else I was worried about.
80
Even the best scientists don't fully understand how genes and environment combine to make us who we are.
81
I was worried that all of this complexity was being overlooked in favor of tantalizingly simple AI predictions.
82
Do you think that the technology is mature enough,
83
accurate enough, capable enough to be giving people this illusion that they have control?
84
The platform, I think, does an excellent job showing the uncertainty and showing the fact that,
85
again, DNA is not destiny,
86
and DNA will never be destiny.
87
People can have certain just genetic dispositions,
88
but there's the whole thing called life,
89
which is there's environment, there's how you're nurtured,
90
how you're raised, nutrition, et cetera.
91
We cannot possibly reduce human life to just a DNA strand.

Por que praticar a fala com este vídeo?

Utilizar vídeos do YouTube para melhorar suas habilidades de fala em inglês é uma estratégia eficaz e envolvente. Através deste vídeo, que explora o uso da IA na seleção de embriões, você terá a oportunidade de mergulhar em um contexto atual e interessante. Ao praticar a shadow speech — ou, em português, "fala em sombra" — você não apenas escuta a pronúncia nativa, mas também internaliza a entonação, o ritmo e a fluência do idioma. Essa técnica, chamada de shadowing em inglês, é ideal para aprimorar sua fala e se sentir confiante ao se comunicar sobre tópicos complexos e contemporâneos.

Gramática & Expressões em Contexto

No vídeo, diversas estruturas gramaticais e expressões se destacam. Aqui estão alguns exemplos que podem enriquecer seu vocabulário e compreensão:

  • “When I talk to a couple” - Esta construção introduz situações e contextos. É útil para iniciar conversas sobre experiências pessoais.
  • “I want to do anything I can” - Uma expressão forte que mostra determinação. Aprender a usar “anything I can” pode ajudar a expressar seus desejos e intenções de maneira impactante.
  • “...especially if you have a family history” - A palavra “especially” enfatiza uma condição. Essa palavra é útil para adicionar nuances ao que você diz.
  • “It’s my right to know this information” - Aqui, a utilização de “it’s my right” mostra como afirmar direitos e escolhas pessoais é importante em debates. Isso pode ser um ponto de partida em conversas sobre ética e decisões pessoais.

Armadilhas Comuns de Pronúncia

Durante o vídeo, alguns termos podem ser desafiadores para a pronúncia. Aqui estão algumas armadilhas comuns a serem observadas:

  • “Alzheimer” - Muitas pessoas têm dificuldade na pronúncia desse termo. Preste atenção no som inicial e nos acentos certos.
  • “Intuitive” - A pronúncia correta pode ser enganosa. Tente repetir várias vezes para pegar o sotaque.
  • “Optimize” - Note a ênfase na primeira sílaba, que pode não ser natural para falantes de português.

Praticando com aprender inglês com youtube, especialmente usando as táticas de shadow speak, você pode superar essas armadilhas e aprimorar sua confiança ao falar. Assim, além de enriquecer seu vocabulário, você se prepara para conversas reais em inglês.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
