Last week someone asked me which AI tools they should be using. The question hides a problem that costs real money: there are more capable AI tools available than any single person can evaluate.
ChatGPT Plus at $20/month. Claude at $20. Grok at $30. Cursor at $20. Copilot at $10. Each with a $100, $200, or $300 variant underneath. Each claims to earn its place.
The real question is not which tool is best. The real question is: which tools subtract more decisions than they add?
