My favorite example, and the ones I show my team and my employer, is that I can have AI look at a string of fields for my database table and generate all the views for the display, add, and edit forms for those fields in exactly the way I instruct, and that saves me as much as 30 minutes every time I do it. If I do this 8 times in a day, that would save me about 4 hours. Especially when those forms require things like lookups and extra JavaScript functionality.
Another great example, is the power of tabbing with Cursor. If I want to change the parameters of a function in my React app, I can be at one of the functions anywhere in my screen, add a variable that relates to what is being rendered, and I can now quickly tab through to find all the spots that also are affected in that screen, and then it usually helps apply the changes to the function. It's like smart search and replace where I can see every change that needs made but it knows how to make it more intelligently than just replacing a line of code - and I didn't have to write the regex to find it, AND it usually helps get the work done in the function as well to reflect the change. That could save me 3-5 minutes, and I could do that 5 times a day maybe, and another almost half-hour is saved.
The point is, these small things add up SO fast. Now I'm incredibly efficient because the tedious part of programming has been sped up so much.
