I mean, writers should have freedom to go where they want with a story, but in many cases it's better to show instead of just telling the reader. This was an instance of telling the reader what they needed to know about Cyclops for this era. We the readers, didn't see him reach this conclusion, and instead are filled in by his dialogue through Polaris and later Corsair. It definitely saves time for what's considered more important for the story, but doesn't do much for flushing the characters out. There's no problem with being fine with the info dump, but it seems obvious that some fans might prefer character work over the story. I think it's just a matter of preference.
As for the hero thing, it has a basic definition. Challenging the idea is one thing, but there are quite a few literary archetypes that comics tend to follow. Also, considering the new team, it's obvious which one Cyclops views as the correct definition.
