I agree that you can't just isolate smart phones in an age of significant technological development.
An intransigent, Luddite approach to technology developments is as bad as the blatant misuse of smart phones. The difference is that if the Luddites want to sit at home, not travel, and barter for their purchases, they are not going to have an impact on culture or society. They are harmless. Saying that you have an ATM card so you don't need a smart phone is ignoring the fact that technology brought about ATMs and plastic cards. Technology introduced cash.
The big difference with technology is it's misuse. A smart phone can be a useful tool in daily life but the cultural impact through social media has been a disaster. There is a thread running about the Thai smile - IMO smart phones have been responsible for it's decline. Pattaya bars are as good an example as you need....attention diverted from providing an attentive service where the girls would rather spend time on their phones than interact with customers.
Any technological development is great in the right hands....take the simple Thai digging tool, the "jorb" ..... an essential building/gardening tool that makes life easier, but misused it can be a deadly murder weapon.
