Aman Sanger says speed will matter more than intelligence for synchronous coding

Aman Sanger of Cursor argues that synchronous coding is nearing diminishing returns to intelligence, with over 95% of queries expected to gain little from smarter models within months.

He contends that extra intelligence matters mainly for asynchronous tasks that take developers hours, while UI work is bottlenecked by user intent rather than model capability. He is therefore excited about frontier models running at Composer-1 speed.
