It can 10x writing code and debugging, but neither of these are a software engineer's day to day. You still need to do code reviews, especially on the AI. It's quite bug free, more than human code, but you still need to explain the product. v0 doesn't quite replace a good product designer. It's not yet at the level it can do architectural work and it doesn't understand the scope or goal of products. It doesn't understand roadmaps. It can't plan the code around where it needs to be in 1 year. You need a proper architect to do this better. The average code it's trained on is from 2019 or so. New models has people write new data for it, but most of this data is not production data. So you're likely using an old design too and it tends to recommend these until encouraged otherwise. Also if you're not using the newer tools like Cursor, Aider, Windsurf, a lot of the contribution of AI is better test coverage. The value that comes with the "agent" tools is they will write and edit code across multiple files, and they save you the trouble of explaining context when you can just share the source code.
