We can expect more "vibe coding", "summoning ghosts" like expressions in the future now officially from Anthropic. I need him to add more videos to his channel on agentic coding. Looks like that won't happen anytime soon.

Recently on the all in podcast, they talked about how Anthropic is probably the next big monopoly. Given how quickly they have been growing and all of the products they are pushing out rapidly (even if they are sloppy), the acquisitions, and the people they are hiring, it feels like that may actually end up being true.

But what is the solution? I don’t think it is safe for a society built on free speech and other liberal values to have a couple extremely powerful companies controlling all our information and imposing their rules and their politics on top of us. It was bad enough under the FAANG companies. This will be worse.

Personally I’m not comfortable with how much power Anthropic is accumulating. And with them partnering shamelessly with Elon Musk to use a datacenter powered by potentially illegal natural gas turbines, I feel like Dario is just not trustworthy.

  Andrej Karpathy - @karpathy

  Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

For better or worse, that's where his audience is.

I'm pretty sure the audience would follow him wherever he goes.

And that’s the point, thank you!

Anthropic should capitalize on this opportunity to undercut their competitor’s platform. They don’t come around often.

applfanboysbgon 17 hours ago|||
Twitter is not a competitor to Anthropic, some random guy with 2m followers leaving would not undercut it in any way, and xAI is literally partnered with Anthropic and selling their compute now.
csallen 18 hours ago|||
I'm sure Anthropic wants him to have as much reach as possible, not abandon his primary distribution channel just to please an extreme minority of the population.

For folks at this scale,

(vs an HN blog author),

networks are communication and dissemination tools,

not principled stances.

For worse. It’s distinctly for worse.

Eh, as someone who isn't terribly interested in seeing non-stop low effort promotion of garbage AI products, I don't mind that they congregate on a site I rarely visit.

The honest reality that people actually like X and use it. They don't make it a point to show off their virtues by boycotting it. Nearly everyone important in the space uses it.
Barbing 18 hours ago|||
I guess they kinda ignore replies and just follow the Karpathy-ies?

Super offending to my sensibilities seeing the extent of slop in replies, and this is months and months ago now. Unbridled poorly prompted GPT-4o replies.

The main posts from smart/funny people are just as good as they would be written elsewhere, yes, but like at a restaurant, atmosphere’s pretty important too… don’t want to eat a tomahawk steak on an airport runway (whether or not the airport’s associated with My Heart Goes Out To You non-Roman non-salutes)

simianwords 18 hours ago||
I don't think the slop problem is that high? Maybe its the people I follow. I just mentally filter out obvious slop anyway. The number of "likes" is a good giveaway for whether it is slop or not.

Must’ve seen a thread that was so horrible I nope’d out hard and of course haven’t checked back.[1] Compounding factor must be how I worry about the “nazi bar” accusations, since that story resonated with me (we know the one, polite-talking guy getting kicked out of bar for seemingly no reason).

If you can screenshot all the good stuff and put it on Mastodon, thank you! ;) (hehe no perfect solutions to this thang)

[1] omg someone prompted GPT to use uncommon words and lowercase letters, and they posted the stupidest model output I’ve ever seen as “their” reaction… it was super disrespectful to make humans read even those few contrived sentences

Anthropic just bought compute off XAI so he's more tightly bound not less.
Barbing 18 hours ago||
That’s a gift to both parties there, yes they sure did (ghosttown Grok servers will get some use, Claude customers able to do things such as… using the service)

Karpathy’s so smart and he has to deal with the reply quality we see on XCancel there… one click away from Hacker News and suddenly every reaction is trash instead of insight and deep insight we see here

(Plus the trash I post, but we’ve got some range, not monotonous spam & model output)

I don't care what their AI is used to generate, as I see that as the user's problem both legally and morally. But I'll be damned if any actions I take make Musk any wealthier, considering what he's doing with what he already has.

Nobody who isn't fully on board with white supremacy (et tu, Andrej?) should be using Twitter at this point.

AI news and ESPN feels interchangeable sometimes.

At least in this case we're talking about someone doing something useful and providing tons of value to the field, not about people being praised for starting a company and raising money.
ssgodderidge 19 hours ago|||
Agreed! OpenAI even bought TBPN [1], who many have equated to ESPN for business. I think that even if Karpathy didn't add any new ideas to Anthropic (unlikely), adding him to the team is an interesting message to give to the market

Maybe he adds some semblance of stability? Anthropic probably is trying to sell it itself as the sane alternative to OpenAI with their IPO coming up choose us we are responsible.
drewbitt 18 hours ago|||
At least with sports teams they entertain me and I can be a fan. For "X person joins Y company" I don't have a reason to care.
Danox 18 hours ago|||
But with the financial community, some semblance of stability is always important particularly with an IPO coming up. Choose us we don’t have a sideshow going on with Elon like the other guys, OpenAI.
DANmode 18 hours ago|||
I’m the opposite.

My “entertainment”, or intrigue, comes from the ability to impact my life.

Other people sporting struggles to catch my attention longer than the play itself, for that reason.

Wouldn't be surprised if companies with too much "superstar" talent suffer from the same issues as sport teams usually do.
