Development

I'm a fresher (6 months exp). As the title says, using AI to write codes is normalised today. I've never had a significant development focused mindset (reading docs, surfing stack overflow etc). Somewhere a code breaks while watching tutorial, felt like doing it later. Maybe because I wasn't coding myself but copying the video and since I started from competitive programming, I always preferred solving to the fullest on my own but development codes don't work that way. I always wanted to and still want to write a complete backend or microservices on my own but I don't know how should I practice it. Infact the AI is so common that people aren't writing the codes themselves and that decreases the urge to learn to manually code. The are companies still asking to code LLD, Machine coding rounds etc. and not to forget multithreading, mutex coding (if happen). What should I focus more on? I do CP in C++, dev in javascript (before) & python (now), and work on Agentic AI in my company (very slow pace). What's could be a good strategy to get out of the dilemmas?
