Does AI really speed up projects by 10x? In my experience, tools like copilot help with the smaller things, but it's bigger things that really matter in a project.

For example, the right database schema or the right architecture I could easily see saving you 10x the development effort, but these are the things copilot is least able to help you with.

Am I misunderstanding something here? Or could it be that what you are finding is that your experience is helping you build faster, and this is being misattributed to AI?
