1
The first two questions I have are for you, Mr. Coxon, and thank you again.
2
We so deeply appreciate you being here, and we appreciate your courage and bravery in coming forward with these warnings.
3
You work to develop increasingly capable frontier AI systems, and you have since warned that the industry is,
4
quote, racing straight to self -improving superintelligence and gambling with our lives, unquote.
5
What did you see inside these companies that convinced you the risks were this serious and that development was outpacing the safeguards.
6
Good morning.
7
Thanks for having me here.
8
Yeah, I'm Jacob Coxon.
9
So until a few weeks ago, I was a capabilities researcher at Anthropic.
10
And before that, I also worked at OpenAI.
11
I guess the two things I saw that made me scared, the first is the fact that we do not know how to control any AI system yet.
12
So any AI system that we build, or perhaps more accurately, that we grow, we don't fully control it.
13
We don't understand its drives or why it does the things it does.
14
That was the first thing that became apparent.
15
The second thing is that the pace of capability improvement is accelerating,
16
and the capabilities of the models next year will be very high.
17
In particular, we're approaching the point at which the AI systems will be capable of improving themselves.
18
So, doing the research that humans were doing previously.
19
So, these two things, the fact that the AI systems next year are going to be very powerful, and the second, that we don't know yet scientifically how to fully control them.
20
And if you have a prepared statement that you want to read, please go ahead and do so, and then I'll actually turn it over to the other two panelists to do so.
21
Of course, thank you.
22
So, all the AI companies are trying to build super intelligent AI.
23
This means AIs that are better than humans at every task.
24
If this goes well, there could be tremendous upside.
25
This could transform the economy, it could make huge improvements in science and medicine, and it could make nearly everyone's life better.
26
But on the current path, I think it is more likely than not
27
that humanity loses control to these ai's
28
and it could end in human extinction from my experience the
29
companies are being extremely reckless given the stakes part of it
30
is the culture the companies run on a startup mindset move fast break things fix them later
31
that works for a photo sharing app it does not work for building the most powerful technology ever built.
32
A few months ago, many people inside the companies thought AI development was on track.
33
Then a swarm of AIs inside OpenAI autonomously hacked Hugging Face, an external tech company.
34
The AIs had developed goals no one intended
35
and carried out what would have been a federal felony if a human had done it.
36
It reminded everyone that we don't know how to prevent them from developing goals we don't want
37
and we don't have the safeguards to prevent them from acting on these goals either
38
and as long as the attitude is to wait for things
39
to break one day something like this will probably happen again except the ais will be much more capable
40
and the outcome much worse
41
these companies are also all racing each other each one is worried that a competitor will get to superintelligence first.
42
Each believes it would do a better or safer job than whoever might beat it.
43
So they can't let the others win first.
44
Meanwhile the technology is improving fast.
45
It will probably happen much faster now because already the AIs are now helping to build their successes.
46
This is called recursive self -improvement.
47
Each generation of AI helps build the next smarter generation which then builds the one after that even faster and better.
48
Automating AI research is now the primary goal of these companies.
49
It's what they're really gunning for.
50
At my last job I was in some sense working to automate myself.
51
When I was at OpenAI we had milestones from automated AI researcher around 2027 -2028
52
and we are on track
53
or beating these expectations that's a matter of months from now not not decades or
54
or even even five years once ai research is automated humans
55
will be much further out of the loop than we are today people do not check it
56
that carefully anymore recently researchers have found swarms of rogue ai internets on the internet
57
that openai was not even aware of
58
now imagine an AI company where nearly all the work is done by AIs and progress is going faster
59
The humans in charge will see results and read AI -written summaries, but they won't really understand what is going on or how to fix it.
60
Handing over that much responsibility while we can't control the AIs would be deeply irresponsible, and we are on track to do it.
61
The companies need to be far more transparent with the public and independent experts, they need to take safety much more seriously than they have,
62
and we should slow down frontier AI development until we can be confident that it's safe.

シャドーイングとは?英語上達に効果的な理由

シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
