“Senior dev Theo argued that real software eventually gets too big for one person to fully understand. His post went viral, and devs had plenty to say. Some agreed while others called it lazy engineering. Former Google engineer Arpit Bhayani pushed back, warning that as devs move faster and rely more on abstractions, th”

“A recent Y Combinator talk shifted the focus from the model to the harness. A harness is basically the scaffolding that connects a model to tools, memory, and integrations. Researchers found that improving this layer can alone push reasoning scores higher than upgrading your AI model. Some harnesses can even rewrite th”
