We’re offloading more and more of our memory—are Siri and Alexa sucking our brainpower?

We humans have always used our surroundings to extend our memory. But is the technology of today enhancing human memory, or replacing it? We plan to gather survey data and run internet-based psychology experiments to find out:
How are people currently using technology for memory purposes?
How well do people understand the technology and their reliance on it?
Are there ways to improve the interplay between technology and human memory?
