What happened with all the organizations that refused to use LLMs because they wanted to protect their code from external access? Are still resisting, or did they realize their code is not so valuable in the end?

AI starts to taking a heavy toil on open source maintainers – the barrier to create a big PR went down, but maintainign code still takes a lot of effort.

Github is uniquely positioned to help maintainers make their work manageable, but I don't think they've cared about it for a while now

Thankfully Wise let me open account with UK number so I can actually send and receive money, but they don't offer joint accounts.

Renting an apartment wasn't easier, I had to produce a lot of documents (and they asked me for a bank account, Catch-22!)

I've just moved in to my new apartment and I'm trying to set up an account to pay for my bills and everything. 2 banks rejected tenancy agreement as my proof, 1 rejected internet bill, @monzo.com just said "no" and that's it.

I just need a simple joint account with my wife but it seems impossible

I'm in the process of relocating to UK, and I'm appalled by how difficult it is to open a bank account as a newcomer.

I tried to open an account before coming here, it didn't work. Then I relocated, and everyone requires utility bills as a proof of address, but I don't have bills yet!

Dziwię się że wciąż są ponad $3T market cap, bo od jakiegoś czasu nie ma motywacji żeby częściej wymieniać ich hardware. Siri to wciąż żart, będą straty po utracie monopolu na płatności w appkach, nie wierzę że pokażą coś wyjątkowego w tym roku

What's actually scary is the number of people in the comments who believe LLMs are lying on purpose.

IT'S A COMPUTER PROGRAM THAT GENERATES TEXT. It does not have an identity, it just spits out the most fitting response based on what it learned from the internet and the books.

I don't think vibe coding is like working with a junior dev... unless the junior dev has attention span of a puppy and memory of a goldfish

Ugh, coding with AI is sometimes wild. I've been trying to rename 20 files, update class names and fix imports with Cursor for like 15 minutes. Every single time it starts modifying other things that I told it specifically not to do

I’m listening to some 2010s hip-hop playlist and I’ve just realized some of these songs are almost 15 years old and I used to listen to them when I was a university student 😫

The teacher said "how Jesus, so tired that he fainted, could get up, move the heavy rock to open the grave, and leave?"

To which I said "to be fair, what's more probable: that Jesus fainted, got up, and left, or that he died, got up, and left?"

1 minute later I was outside the classroom

Got kicked out of religion class for questioning the resurrection πŸ˜…

So in Poland we have religion classes and one day my teacher was "debunking" myths about resurrection. One of the myths was that Jesus didn't die when crucified, but just fainted...

And it's probable we won't survive even the next few thousands, so it's understandable that there are no civilizations that:
* survived long enough to travel freely across universe
* happen to live close enough to us to pass by
* and whose presence we would be able to notice

What I mean is that on average people cannot distinguish facts from lies, they believe simple but wrong slogans more than complex but accurate explanations.

As a specie we've been on earth for ~150,000 years, which is not even a blink of an eye in the age of universe (0.001%)

We are unable to deal with the threat from within: the people who are willing to sacrifice millions of lives for the sake of their own wealth. Instead we chose these charlatans as our leaders. And we don't learn our lessons.

It's possible we reached maximum complexity we can handle as a civiliation

People often wonder why we haven't seen extraterrestial life yet here on earth.

Looking at humanity right now I think I know the answer: civilizations eventually just destroy themselves form the inside.

Climate change, the biggest threat humanity has seen, is not enough to unite us.

The whole Apple Intelligence rollout is a mess. I don’t even have access to it in EU and still it makes my iPhone experience worse. Here’s what I see when I go go my setting and start looking for β€œmessages”

Other countries struggle with it, too. In the Netherlands they’re much more effective but also there’s only so much a single teacher or caregiver can do, so the cost of education and healthcare goes up (either by increasing prices or taxes)

Omg I’ve always known of that phenomenon but didn’t know it had a name, good to know!

These tools can really boost productivity, but people need invest time in learning them. Throwing them at users and saying β€œhere you go, use it” is not helpful, people will just be disappointed by the limitations and quirks of LLMs

What's the point of AI assistant on Quora? If I wanted to get a ChatGPT-like response I'd just open ChatGPT. I opened Quora because I expected answers from actual, living human beings, not a bot
