Day 011 — Speaking: テクノロジーと日常生活

Absolutely, yes. I use it practically every waking hour. It's the first thing I check in the morning and the last thing I look at before sleeping, which I know isn't ideal.

Mainly for messaging — I use Slack for work and LINE for friends and family. I also use it to read tech articles during my commute.

Without a doubt, yes. Research shows that excessive screen time affects sleep quality and concentration. That said, for many people it's tied to their job, so it's not easy to just switch off.

I have, actually. I tried setting app time limits using Screen Time on my iPhone. It was partially successful — I reduced social media use quite a bit — but I still picked up the phone out of habit constantly.

I think it's genuinely both, but on balance, I'd say easier. For someone in my field, tools like cloud computing and version control systems have dramatically reduced the complexity of development. However, I do feel a kind of digital fatigue from being constantly reachable.

The most obvious one is vulnerability. When systems go down, entire businesses can halt. On a personal level, people are losing the ability to navigate or do mental arithmetic. There's a real risk of our fundamental skills atrophying.

I think AI will automate many routine cognitive tasks, shifting the human role toward creativity and judgment. In tech, AI coding assistants are already changing what developers spend their time on — less on boilerplate, more on architecture.
