The same question can be asked of us as app developers. AI is moving fast, results improve quickly, and many engineers have started adopting tools like ChatGPT or Cursor AI. While predicting the future is always hard, I think it's fair to say AI already plays an essential role in development today. While it's not able to take control over app development completely, it already helps developers build apps faster. ​This article from The Pragmatic Engineer resonated a lot with me. In fact, I truly believe that experienced engineers who know how to optimize development using AI will have the most value in the future. AI can get you to 70% of what you need, but without the skills to optimize the output, getting a high-quality app into the App Store will be hard. Let alone thinking about great UX! If you're still worried that AI might replace your job, try shifting your perspective to the opportunities it creates. During the gold rush, it wasn't just the miners striking gold who found wealth—those who supported them by offering services like laundry or security also became incredibly successful. So, what role can you play in the AI gold rush? Want to have your question answered next week? Ask your question via this form (anonymously) or reply to this email with your question.
