This tweet is not at all in line with the article. From the article:
> Dr. Hinton said he has quit his job at Google, where he has worked for more than decade and became one of the most respected voices in the field, so he can freely speak out about the risks of A.I. A part of him, he said, now regrets his life’s work.
> Dr. Hinton, often called “the Godfather of A.I.,” did not sign either of those letters and said he did not want to publicly criticize Google or other companies until he had quit his job.
As Hinton says in his tweet, this clearly implies that he left to be free to criticize Google.
And the following quote is not really consistent with the other part of Hinton's tweet, that "Google has acted very responsibly":
> Until last year, he said, Google acted as a “proper steward” for the technology, careful not to release something that might cause harm. But now that Microsoft has augmented its Bing search engine with a chatbot — challenging Google’s core business — Google is racing to deploy the same kind of technology. The tech giants are locked in a competition that might be impossible to stop, Dr. Hinton said.
> said he did not want to publicly criticize Google or other companies until he had quit his job.
This seems to me to be the only line in the article that is incorrect or incongruent with what he is now saying - specifically the use of “Google”. It’s about ~10 paragraphs in on a ~20 paragraph article (I’m eyeballing).
> Dr. Hinton said he has quit his job at Google, where he has worked for more than decade and became one of the most respected voices in the field, so he can freely speak out about the risks of A.I. A part of him, he said, now regrets his life’s work.
So perhaps he regrets the direction of his work, but not the fact that it occurred at Google.
> As Hinton says in his tweet, this clearly implies that he left to be free to criticize Google.
No, it does not imply that at all. The One could interpret it that way, and they would be wrong to interpret it that way, because it doesn't imply that, but I can see how someone without a good grasp of the English language might feel it implies that. That's nuance.
But no, it does not imply that at all. And any suggestion that it does imply that is conjecture at best, and not backed up by Dr. Hinton's other tweets on the matter.
It appears to me that it is you who is misunderstanding the comment you quoted. Here is the context:
>> Dr. Hinton, often called “the Godfather of A.I.,” did not sign either of those letters and said he did not want to publicly criticize Google or other companies until he had quit his job.
> As Hinton says in his tweet, this clearly implies that he left to be free to criticize Google.
The comment is saying that Hinton, in his tweet, is saying that the article's statement "he did not want to publicly criticize Google... until" is misleading, and he did not leave in order to criticize Google. This is in fact what he said, and this is what cbolton is saying that he said.
> Dr. Hinton said he has quit his job at Google, where he has worked for more than decade and became one of the most respected voices in the field, so he can freely speak out about the risks of A.I. A part of him, he said, now regrets his life’s work.
> Dr. Hinton, often called “the Godfather of A.I.,” did not sign either of those letters and said he did not want to publicly criticize Google or other companies until he had quit his job.
As Hinton says in his tweet, this clearly implies that he left to be free to criticize Google.
And the following quote is not really consistent with the other part of Hinton's tweet, that "Google has acted very responsibly":
> Until last year, he said, Google acted as a “proper steward” for the technology, careful not to release something that might cause harm. But now that Microsoft has augmented its Bing search engine with a chatbot — challenging Google’s core business — Google is racing to deploy the same kind of technology. The tech giants are locked in a competition that might be impossible to stop, Dr. Hinton said.
