Evolution Beats Design

Guillermo Rauch believes that the success of technologies like JavaScript is better understood through the lens of evolution and natural selection rather than intelligent design. He argues that technologies that start simple but have room to evolve often win over more complete or powerful alternatives.

• "Worse is better" is a paradigm from the early internet days

  • Sometimes constraining a technology makes it more predictable
  • Less powerful but more predictable technologies can become the foundation of successful systems

• Technology success follows evolutionary patterns

  • Brendan Eich (JavaScript creator) points out that technologies succeed through natural selection
  • The article "What would Charles Darwin think about clean slate architectures" explores this concept
  • JavaScript evolved from a simple piece of code to something sophisticated over time

• JavaScript's evolutionary advantages:

  • Started as a minimalistic language that could be embedded directly in markup
  • Initially seen as limited: "it can't be fast, it can't be typed, it can't scale"
  • These limitations were temporary, not fundamental - they could be overcome through evolution
  • JavaScript now runs on every device on the planet inside web browsers - no other language has this advantage

• Success comes from finding asymmetries or unfair advantages

  • JavaScript beat alternatives like Flash (killed by Steve Jobs) and Java applets
  • It was initially perceived as a "toy" but this underestimation created opportunity

• The power of minimal viable surfaces

  • "What is the minimum surface that you can ship on top of which evolution can be bootstrapped?"
  • Better to ship something minimal that can evolve than aim for completeness in the initial version
  • Constraints like deadlines force reduction and focus on essentials
  • JavaScript was created in just 10 days due to Marc Andreessen's deadline

• Reduction is the path to success

  • "If you're truly brilliant... you have to delete and delete and delete"
  • Constraints like YC's three-month timeline act as forcing functions for reduction
  • Human nature tends toward adding more, but success often comes from focusing on essentials
