This sounds like a good problem to have. :)

I’m glad you had such a nice time with your friends.

β€œYou realize it’s our technology, and this elaborate structure of civilization, that gives us the freedom not to be present, which is to say conscious. We normally think we’re more conscious than animals, but there’s a sense in which they’re more conscious than we are.”

β€œIt’s not that people on social media or engaging with chatbots are not conscious. It’s just that the space of their consciousness is being manipulated on purpose.”

This leads me to reflect on how many of the books I loved when I was a kid featured kids going around on their own β€” on bikes, on foot, etc.

And then I contrast that to how many (i.e. nearly zero) kids I see going around like that these days. πŸ˜”

πŸ’₯ Just came up with an idea for a series of picture-book whodunits for little kids.

Do I need another good idea for a project? NO. Will I at least write it down? Sure.

This skeet and the replies make for good and thoughtful discourse on the nature of labor, skill acquisition, and knowledge work.

It’s different in social sciences where the writing and the thinking are inextricably linked, and where the β€œpseudo code” product is the final product, because they end user is also human and not a machine. 2/2

What they fail to get is that predictive algorithms for coding are transformative because they streamline the β€œturn these task specs from human language into computer language” part of the job. They don’t transform the thinking part of figuring out which tasks need doing and why. 1/

And, you know, not for nothing, coding and historical research and writing are wildly different skills with wildly different methodologies and goals.

Especially in academia, news & art, it’s important that *people* create what we read/appreciate because what matters to people about those things are the insights, trustworthiness and interiority of the people making them.

BTW, my oldest saves on Bluesky are only from late 2024. I just spent a few minutes (!) scrolling all the way down to my oldest saves on Instagram . . . from February 2018. πŸ˜΅β€πŸ’«

As I've said before (see nested skeet), this purgation project means you should expect random reposts of stuff that could be months or years old.

I'm sure I'll also post about books I'm reading & other interesting stuff I come across, but mainly I'm resetting my habits to get away from saving posts e-mails, papers, etc. "for later" β€” or a version of "later" that never comes.

...which is tied to stuff some of y'all have heard me say before/recently about purging bookmarks (and saves, e-mails, papers, whatever).

So for the next however-long-it-takes, I'm replacing scrolling with purgation.

a man with curly hair and a beard says it bothers me leonardo Alt: a man with curly hair and a beard says "it bothers me".

Y'all, I love social media for the interactions I have with neat people β€” but all the browsing & scrolling is undermining my:

β€”cognition
β€”mental health
β€”time & task management
β€”spirit (?)

So I'm trying an experiment...

PLEASE take my hard-won advice for tough times: Don't oversell the badness of a thing β€” to yourself or others.

If it merely sucks, say "Ugh, this sucks" β€” not "FML this is so disheartening."

It's SO common to hear people make a situation worse β€” & hamstring their own response β€” by exaggerating it.
