I'm not an economist, but I don't know how the AI bubble CAN crash at this point. Money out of AI has to go to somewhere, and there's nowhere else for it to go. In 2025, AI investment exceeded all consumer spending.
Bubbles are where the rich store their money now, the product is irrelevant.

We liked pretty much everything we did. The top three things I enjoyed more than I thought I would:
3) Hot springs
2) Friðheimar (the tomato greenhouse on the golden circle)
1) A tour inside a glacier...I still dream of that unearthly warm blue light

Most of the Republican base were told how to feel about it before they even saw it, if they saw it at all. They are on the receiving end of a slick propaganda machine that had sitting senators praising his "toughness" within the hour.

That would be the inimitable Mabel (named after the equally unhinged Gravity Falls character).
"Fun" fact: She hasn't stopped growing in the 18 months since that picture was taken! We can't decide if she is the Least Dane or the Greatest Weasel.

I yearn for the day when I see one of these Busytown bad boys hard at work...though I worry that the current administration's plans for the Post Office will not include new goofy duck trucks.

Related story: Back in 2011, Bont started making their own plates. I got some new skates with pre-mounted bearings, and they were the flimsiest imaginable bits of cheap plastic. Both plates snapped the moment I put pressure on the toe stops.
So, shoddy quality control may be a brand standard.

Google used to actually compute things like this when you typed it into search. It's not hard, these are all buttons on a pocket calculator.
Google has replaced this auto-compute function with genAI, and the result is _badly_ wrong! The correct answer is not negative!

One of my officials' group chats is playing a game to see who has officiated in US states and CA provinces coast-to-coast.
I've got 23, but I didn't make it over the Rockies. I guess I've gotta do RollerCon or Cactus Cup.

The first no-scrimmage scrimmage night of the off-season has me bummed. At least I had an amazing year of derby!
My favorite part was easy: working with this crew at NA NE regionals. The absolute best part of reffing is clicking as a crew, and working with these beasts was such a privilege.

Name a TV show you feel like no one remembers but you:
O'grady was a hilarious and bizarre evolution of Home Movies with most of the same voice cast, and yet it seems almost completely lost to time
