Today’s PR workflow is only the first generation of product form!

Cognition wanted to be a generational business from the beginning.

Some outsiders feel that all opportunities have been taken away by model laboratories, or that the form of today’s coding product is almost finalized.

His reaction was very direct: If you think that today you open Devin web app, write instructions, get PR, and review again, this will become a permanent form of software development, then of course you will think that nothing will change.

But he believes there will be at least 10 generations of product experience ahead.

Today’s PR workflows are just early interfaces, and the real innovation will happen in task expression, context understanding, validation, collaboration, permissions, and delivery processes.

This is also the most important point to pay attention to when looking at agent products: don’t just look at how smooth the current UI is, but also look at whether it has room to continuously rewrite the software production process.
