Asked about Attention, conceptually

Why did transformers replace recurrent networks?

An answer that works

Recurrence processes sequentially, so distant information degrades through a carried summary and nothing parallelises across the sequence. Attention connects any two positions directly and computes all positions at once, which is what made training at scale practical.

Reading an answer is not being able to give one. The section that teaches this is Attention, conceptually, 8 hours of Transformers & attention.
