How would it not be a big unlock? If the answers were instant I could stay focused and iterate even faster instead of having a back-and-forth.
Right now even medium requests can take 1-2 minutes and significant work can take even longer. I can usually make some progress on a code review, read more docs, or do a tiny chunk of productive work but the constant context switching back and forth every 60s is draining.
current speeds are "ask it to do a thing and then you the human need find something else to do for minutes (or more!) while it works". at a certain point at it being faster you just sit there and tell it to do a thing and it does and you just constantly work on the one thing.
cerebras is just about fast enough for that already, with the downside of being more expensive and worse at coding than claude code.
it feels like absolute magic to use though.
so, depends how you price your own context switches, really.
