What Does The Ending Of Black Panther Really Mean?

8. ...And They're Technology Could Help Tony Stark

As well as seeking to help the needy, T'Challa and Shuri talk about helping other countries by introducing them to their technological superiority - not least in the medical field.

And it would seem that we'll see them cooperating with more private groups as well - like either The Avengers or Stark Enterprises (assuming the two are even separate now) - because the nano-technology used in the new Black Panther suits seen in the movie will presumably lead to Tony Stark's Prime Armour in Infinity War.

Unless he's independently worked on the same technology, it makes sense that Wakanda's cooperation with the US and Stark himself (assuming he can get over Bucky's protection by T'Challa) would see him adopt some of the new tech for his Bleeding Edge-style suit.
