You are not alone! I strongly agree and I feel like I am losing my mind reading some of the comments people have about these services.
I swear the people posting this stuff are just building todo list tier apps from scratch. On even the most moderately large codebase it completely breaks down.
For me it's an additional tool, not the only tool. LSPs are still better for half of the things I do daily (renaming things, extracting things, finding symbols, etc.). I can't imagine using AI for everything and even meeting my current velocity.
