Websites Are Boring — Embrace a Bifurcated Web
The author argues that widespread use of templates (Shopify, Squarespace, Webflow) and optimisation-for-conversion has homogenised websites, eroding brand distinctiveness. With the rise of AI, agents, and agentic commerce, discovery is shifting toward machine-driven flows that risk reducing websites to backend databases. The piece proposes a bifurcated web: a ‘Silent Web’ of machine-readable feeds for agents and a separate ‘Experiential Web’ focused on rich, human-first brand experiences powered by creative use of AI. The article cites industry projections for large economic impact from agentic commerce and multiple survey statistics showing consumer trust and adoption of AI shopping tools.
- The article states the rise of Shopify, Squarespace, and Webflow templates has produced mass homogenisation of websites.
- A McKinsey projection cited in the piece estimates agentic commerce could generate $1 trillion in the US B2C retail market by 2030 and $3–5 trillion globally.
- The article cites that 58% of Gen Z and millennials trust an AI agent to compare prices and recommend options.
