Well, it’s a quick take, and no doubt data will come in, but it sure looks like based on today’s evidence that a lot of pro-Trump and pro-AfD bot work depends directly on Russian data centers.

If you need a pickmeup, Ukraine struck and destroyed a Russian data center last night, reducing Russian bot traffic by 50%, dropping online pro-AfD discussion to zero, cratering MAGA traffic, and making Elon big mad. Just in time for the mid-terms. Slava fucking Ukraini.

There's little that's "inevitable" about AI | deadSimpleTech
The glib response here would be to say that no technology is ever inevitable and that everything is contingent. This has the advantages of being technically true and sounding wise, but unfortunately technologies very much exist that a reasonable person might well label that way. Firearms are a good example of the latter case: once they've been developed, you quite quickly hit the situation where if you want to maintain your independence and safety in a society, you have to either use one or have one used on your behalf: no other options really work.
