It's becoming increasingly difficult to fight the desire to become a hermit in the woods.
The comments on this are all about how sweet it is and I feel insane. Using AI to make fake memories of your grandma with dementia and telling her they happened and then filming her reaction

Problem with AI is not technology, problem is unresponsible people abusing this (and any other) technology for their own profit and fame.
Any software (including AI models) should be used to make society better. Instead brightest of us optimize selling ads and stealing personal data.

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software.
Just fuck you. Fuck you all.
I can't remember the last time I was this angry.

to me
Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

Xmas is coming... the time of year when some random non-tech weird uncle will try to convince me that my job is dead due to (probably woke) AI and I should become carpenter, and I'll be like "dude, I'm the one building those tools that are supposed to kill my job"

Whenever I see someone doing "all the office jobs will be dead in 3 years due to AI, you all will need to change jobs to some physical things" I'm thinking... "so if you're sure of this future why haven't you done this change yet?"

Hot take after few hours of #fsharp coding today.... Ionide is kinda good.
Still better than Rust editor experience. Not as great as TS/JS, but I guess that's kinda expected.

People hating that some software was build with use of AI will be mind blown that vast majority of existing software have random snippets of code from random people from Stack Overflow in it all over the place :>

Copilot inline suggestions + NES is still the best use of AI for coding.
I guess it’s because I’ve designed UX of both :>

Software development is about people. Not about tools, ai, agents. Not about code.
The people. Building any software requires collaboration, building any software requires understanding needs of your users.

AI is not a problem. Capitalism is. Just like with any other technology in recent years - internet, oss, mobile phones, etc all has been perverted by capitalism.

Those people ain't architects of anything. just a modern car dealers, pushing stuff, that better people built, to do things it was not designed to do.
I guess it's fitting that it's a reimagined, worse version of someone else's artwork
