OpenAI cofounder Andrej Karpathy put it simply: most businesses still expect people to navigate web pages, click buttons, and follow complex instructions to enter data. He called this approach "rude" when an API could handle the whole thing.
Perplexity is taking the same logic a step further. CTO Denis Yarats said the company is ditching MCP internally for raw APIs and CLIs.
We need to start treating the UI as an optional interface, not the primary one. Good APIs and CLIs from day one are a strategic advantage: AI agents and developers can use your product without a human clicking through it first.
