Surprisingly healthy mindset when it came to electronics coming from a self-concious boy who had trouble learning from his past and using it to improve on what he sees as a damned future. But Yondu's knowledge on the matter is limited, and even if he were able to put all that together? Even if it was voiced? He'd probably not point that out and expose his fragile underbelly.

"Yeah I'd come with ya."

He's only speaking to a few people, just in case he doesn't see them again. Good-byes of sort. If Idia wants to show him something, he has the time. It might be his last chance.
