I don't think that's a fair characterization of what Ehsan said.

I'd say it this way: the difference between being able to edit 10 minutes
of audio vs 20 minutes is much less significant then being able to edit 10
minutes vs 1000 minutes. We need to ensure it's not too hard to achieve the
latter, and if we do, the former is uninteresting.
