I like how it addresses that most people are actually ignorant of the underlying principles of all modern technology and couldn't replicate it to save their lives.
Beautiful deconstruction of the isekai trope—remove the self-insertion and wish-fulfillment and plot-armor, and all that's left is regular humanity. You make do, and things are more or less okay.
For real tho, at least this dude had his art, I wouldn't have crap, like how the hell will my coding and computer network knowledge have any use in a fantasy world...
That's certainly the most realistic isekai story you can get...
