Read the articleThe risk of not using AI is now bigger than the risk of using it.
Let the AI write it, and shift yourself to review and direction โ if the very people building these tools already work that way, it's only a matter of time before everyone else changes too.
Japan's IT industry can no longer wave this off with "that's not us." Before worrying about the risks of using AI โ data leaks, accuracy, copyright โ we've entered the phase of facing the gap that widens by not using it.
The gap between people who touch AI and people who don't may be small in a day, but over months and years it opens into a career-sized divide. Rather than dismissing it as "not relevant," getting on the side that asks how to make it relevant is the most important call you can make right now.
