Even if you limit your AI experience to finding information online through deep research it's such a time saver and productivity booster that makes a lot of difference.
The list of things it can do for you is massive, even if you don't have it write a single line of code.
Yet the counter argument is like "bu..but..my colleague is pushing slop and it's not good at writing code for me", come on, then use it at things it's good at, not things you don't find it satisfactory.
When I was early in use of it I would say I sped up 4x but now after using it heavily for a long time some days it's 20% other days -20%
It's a very difficuly technology to know when you're one or the other.
The real thing to note is when you "feel" lazy and using AI you are almost certainly in the -20% category. I've had days of not thinking and I have to revert all the code from that day because AI jacked it up so much.
To get that speed up you need to be truly focused 100% or risk death by a thousand cuts.
- I think given public available metrics, it's clear that this isn't translating into more products/apps getting shipped. That could be because devs are now running into other bottlenecks, but it could also indicate that there's something wrong with these studies.
- Most devs who say AI speeds them up assert numbers much higher than what those studies have shown. Much of the hype around these tools is built on those higher estimates.
- I won't claim to have read every study, but of the ones I have checked in the past, the more the methodology impressed me the less effect it showed.
- Prior to LLMs, it was near universally accepted wisdom that you couldn't really measure developer productivity directly.
- Review is imperfect, and LLMs produce worse code on average than human developers. That should result in somewhat lowered code quality with LLM usage (although that might be an acceptable trade off for some). The fact that some of these studies didn't find that is another thing that suggests there shortcomings in said studies.
AI multiplied the amount of code I committed last month by 5x and it's exactly the code I would have written manually. Because I review every line.

For some things LLMs are like magic. For other things LLMs are maddeningly useless.
The irony to me is anyone who says something like "you don't know how to use the LLM" actually hasn't explored the models enough to understand their strengths/weaknesses and how random and arbitrary the strengths and weakness are.
Their use cases happen to line up with the strengths of the model and think it is something they are doing special themselves when it is not.
Feel free to cite said data you've seen supporting this argument.
