“When all you have is a hammer, everything looks like a nail” — How does this quote from Denis Villeneuve’s Arrival take on special relevance in connection with the film's theme?

In Denis Villeneuve’s Arrival, characters Louise Banks and Colonel Weber bring up the idea that, when all you have is a hammer, everything looks like a nail. This is an intriguing idea that basically means that, whatever your background, training, or experiences happen to be, they shape how you see solutions. When presented with a problem and you are in the military, you see a military solution. If you are a politician, then you see a political solution. On one hand, Banks is concerned by this idea, because, if the aliens are introduced to humans in a specific way, it will form the basis for all their interactions. On the other hand, this idea is reflected in how the different groups want to deal with the aliens.
