If you’re critical of the type of flight that Michi took up there — that’s fair, and you’ll see that we touch on some of the concerns you might have. Also, they’ve stopped doing them now, so you can be happy either way.

Not only is it our longest episode by far, but our guest will give you an in-depth first-hand account of what it’s like to be the first wheelchair user ever to visit space. As always, what our dear space nerd friend Michi has to say is both fascinating and sincere. You won’t want to miss this one.

Sorry to plug German-language stuff, I swear I’ll stop, but I need y’all to know that our Nerds at Work Podcast is now also available on my colleague @christianscharun.de‘s YouTube channel (audio only). And it’s good timing too, because our current episode is pretty unique:

Here’s the thing — I think I can sort of understand the mindset of those gun-totin’, God-lovin’, Constitution-huggin‘ full-blooded conservative Americans, at least to a certain degree.
But by all rules of logic and ideology, they should be the ones most up in arms about this stuff. Where are they?!

As a psychologist, I’m curious as to who would even be interested in this (presumably only some bereaved, and only for a short time) and whether it would actually be damaging, which we just don’t know yet.
But as a human, I just want to burn down this whole nonsense tech with the fire of my rage.

I have relatives in the US that I haven’t spoken to in years because I know they’re Trump voters. I’m considering unblocking them on Facebook just to send them this clip alongside the words “you wanted this”

My personal opinion: So long as it’s not overly radioactive, it can go on a burger. I’ve eaten things you people wouldn’t believe. Marshmallow burgers with beef and chocolate sauce. Burger patties that were marinated in absinthe. All those steamed hams will be lost in time, like tears in rain.

My reason for saying it was because the LinkedIn crowd seems unreasonably pro-AI to me, but it’s possible that that’s just my bubble. You’re right that the comments are reasonable, but I didn’t know that yet when I posted my screenshot here

Anthropic being honest about the damage they’re doing is probably the result of them reading my popular science book which they stole.

There’s discourse on German journalism Bluesky about using quotation marks around the word “documentary” when discussing the Melania movie. (Same thing happens when people write “President” Trump)
Here’s the issue with this: Your audience has no idea what the hell it means.

…people will call you out on that. They’ll ask for the criteria you’ve used to determine the movie is an image film. And that uncomfortable space is where actual journalism happens. You give people your informed view and defend it where necessary. Using quotation marks is the opposite of doing that.

As a journalist, your focus should be on saying what you actually mean, not tip-toeing around it. If you don’t think the movie is a documentary, what do you think it is? Some seem to think it’s an image film. If you think that’s what it is, then call it that. But then, of course…

It’s obviously a statement about legitimacy: You don’t think the status as documentary (or president) is justified. But in what way? How does it not fulfill your criteria? What *are* the criteria? In case of Trump: are you talking about rigged elections? Or just that he’s not doing his duty?
