The language everyone loves to hate is still powering billions of devices but that doesn’t mean it’s thriving. Let’s talk about why it refuses to die. If I had a dollar for every time someone announced Java’s death, I could probably retire and spend my days writing Rust that neve … | Continue reading
Thats right, prediction are not the same as calculations, and LLMs don't calculate, they predict the next word. Stanford's HELM report shows GPT-4 hits 90%+ accuracy on math tasks. But 90% accuracy in financial calculations means 1 in 10 transactions could be wrong. Would you shi … | Continue reading
