Naima: The proposed new computer system, once we fully implemented it, would operate more smoothly and efficiently than the current system.
Naima's 1st claim
Once implemented, the new comp system would be smoother and more efficient than the current system.
Does Nakai argue that the new system would not be smoother or not be more efficient than the current system?
No, they don't talk at all about its potential smoothness or efficiency.
Naima's 2nd claim
We should devote the resources to convert to the new system as soon as possible.
Does Nakai argue that we shouldn't devote whatever resources we'd need to switch to the new system as soon as possible?
Yes, they say we should keep the current system for as long as possible.
Goal
Since person 2 disagreed with one of person 1's explicit claims, we don't really need to go any deeper. We have a good prephrase. Let's look for an answer circling around whether we should convert to the new system as soon as possible or hold onto the current system as soon as possible.
