Can analysis ever be automated?

benn.substack • 1150 implied HN points • 01 Aug 25
đź•ą Technology Software
  1. Automating analysis is tricky because we can't confirm if the results are accurate without understanding how they were made. This means we often have to trust the source instead of verifying the information ourselves.
  2. AI can create complex spreadsheets or charts but we can't easily check their correctness. Unlike other software, we can’t just test if a chart 'works' without digging deeper into its creation.
  3. In finance, companies are using strategies like buying crypto to boost their stock prices, even if these tactics seem irrational. This shows that sometimes getting attention matters more than the actual business fundamentals.

When "I Built" Became "I Ordered"

decodebytes • 87 implied HN points • 19 Jan 26
đź•ą Technology Software
  1. Saying "I built" used to mean someone had done the hard, iterative work and gained deep understanding.
  2. Today "I built" often just means you described what you wanted and AI produced it, so the person may lack scar tissue or real intuition about how it works.
  3. That shift reduces the credibility and meaning of claiming to have built something and makes genuine craftsmanship harder to recognize amid mass-produced outputs.
