What you used to think

  • "AI is a smarter Google — I ask, it answers"
  • "I need to spell out every step"
  • "AI can't do anything complex"

What's actually true now

  • AI agents plan their own steps, use tools, and deliver finished work
  • "Research 5 competitors and make a spreadsheet" just works
  • You review results, not babysit the process

What to do about it

Next time you have a multi-step task, try giving the whole goal to Claude or ChatGPT instead of breaking it into pieces yourself. Let the agent figure out the steps.
