AI is the new cloud. There's no market for people or companies who aren't committed to it. If you're a dev who refuses to use AI, no company will hire you; and should a company decide not to use AI they will have a hard time retaining devs (and they will need more devs). Their investors and big-ticket customers will also think twice before signing off on major commitments.

So yes, use AI. Don't nitpick the costs and benefits. The world is headed this way; if you want to develop software for a living and afford to eat, you need to be too.
