The real skill gap isn't coding anymore, its knowing when the AI is wrong

Something i've been noticing that nobody really talks about. we all debate whether AI will replace devs but the actual problem is happening right now and its subtle i work with a mixed team, seniors and juniors. the juniors are faster than ever at shipping code. like genuinely impressive output speed. but when something breaks in production? complete freeze. because they never built the mental model of how the system actually works, they just assembled pieces that an AI gave them and heres the thing - the AI is usually like 85% right. thats the dangerous part.
