Sorry I'm not more open-minded about LLMs, it's just some fucking maniacs shoveled out a bunch of useless bloatware featuring that technology, did not give me any chance to opt out, reorganized the entire economy around it, zeroed out gains made by green energy, and made it impossible to buy RAM

“Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. 

Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.”

— Carl Sagan

"The program has detected a signal sent from another galaxy, but we need to upgrade to a paid version before we can reply."

The screen reads "Choose a plan To unlock replies: 1. Student 2. Basic 3. Pro 4. Expert "
