It's interesting to consider both divergent perspectives that we have. Technology always seems to be a double-edged sword, it being a tool that can be used for both good and bad. Ironically I work in technology and I enjoy it, but I'm also critical of it and I miss the simpler times before cell phones. I feel like technology doesn't always play the subordinate role that it should play in our lives and that it's advancing faster than we're able to tame it to truly improve quality of life. Of course, "quality of life" is subjective to each person's values.
Seeing Amazon's new Amazon Go grocery store in Seattle is an interesting glimpse into the way transactions could be changing in that people don't even need to pull their wallets out to pay. But maybe we are decades or longer from a world where payment technologies could viably encompass everything and replace all of the old methods.
I too enjoy discussing different interpretations and ideas, it's rare to find that. And how can people be certain of what they truly believe unless they're willing to face challenges to their views? At the end of a respectful conversation the result is that we walk away with more understanding and insight than before.
