Thankfully my 2 weeks vacation in #Iran have already made it de-facto impossible to get into US of A. This crap would make it even less likely that I would want to.
In addition to 5 years of social media history, CBP would also require tourists to provide all phone numbers used over that period, any email addresses used in the past decade, DNA and iris scans, and the names, addresses, birthdates and birthplaces of family members

If there is one thing that is certain, is that a data breach will occur. It's not a matter of IF, but WHEN (and if the company will actually announce it).
So giving Google (or any company) your ID is a suicidal decision.

Oder noch besser: Sendung in Zustellfahrzeug geladen und 1min später: Zustellung nicht möglich.

This shows how little effort (comparatively) goes into "influencing" on Twitter. They do not even bother obfuscating the location by using a VPN!
I’m still enjoying how MAGA Twitter will never live down that they’re all troll farms from Russia and Bangladesh. The whole MAGA ‘movement’ has been fake bullshit from top to bottom from the very beginning.

Which makes it all the more frustrating that applying for funds for fundamental research is always a massive uphill battle - especially for small groups.😒
Every machine in a Hospital that diagnoses your body without cutting you open is based on a principle of Physics, discovered by a Physicist who had no interest in Medicine.

As always: It's complicated.
LLMs will almost surely not help.
Focused use of the methods for modelling and prediction in complex systems (e.g. LSTMs for the power grid) may turn to be a very useful tool.
Both are subsumed under "AI", but have generally vastly different levels of care applied.

There is a big push at Cop30 to reframe AI as a way to cut, rather than add to, planet-heating emissions.
But is 'AI for good' really a force that will help confront the climate crisis? www.theguardian.com/environment/...

AI is guzzling energy for slop content – could it be reimagined to help the climate?
Some experts think AI could be used to lower, rather than raise, planet-heating emissions – others aren’t so convinced
