IMHO - if a brick and mortar store or chain owner does not embrace technology to its maximum capability, they will fly the way of the dodo. With that being said, adopting new technologies like iBeacons will certainly help.
I believe retail needs to embrace the customer "360" to survive. They need to know who their customer is and what technologies they use to help them make their buying decisions. They'll technically need to address the customer before they get to the store, while they are in it and after they leave. They should be using tech to guide the customer into the store based on proximity triggers and creating purchasing behavior profiles using advanced analytics platforms.
Use of in-store guidance systems to help customers get in and get out (or to guide them to "recommendations" and "specials just for them") should be deployed and activated again using proximity and permissions. Frequently Bought Together items should be flagged once a customer picks up or lingers near a particular product or section.
Not sure if a retailer is going to be viable long -term (maybe 10 years) without a complementary online component, but at the very minimum, they should be embracing all the B&M tech they can to create a compelling shopping experience.
