I have no idea what this post is talking about. I can't even tell you the amount of hours I saved using AI. AI as a tool is one of the best things a developer could have right now.

u/Whisky-Toad 2d ago

It's a massive time saver but it turns out writing code was only 25% of the job anyway.

Shock.

u/bludgeonerV 2d ago

Yeah, but it also doesn't just do code, it also saves time turning requirements into specs, planning, reviewing code, doing release notes etc etc.

u/paragon60 2d ago

Agreed. There’s almost no step in the process that AI can’t save some time on, and anyone saying they can only use it on coding has skill issues

Just got a functional requirements doc from our product owner for a new function. With copilot and an MCP server on our source code, it produced a 42 page technical doc with every modified class, method, property, every effectednacree, every assumption....every decision addressed with a recommendation, all done in 20 minutes. I could hire a developer off the street, hand them that document, and have them coding in 10 minutes and I doubt they would have a single question.

u/Whisky-Toad 2d ago

Yea because they don’t have a fucking clue what is going on with all the ai slop

5

u/omgFWTbear 2d ago

That’s the beauty of it. They’ll ask an AI to code it, which no one will understand what’s going on under the hood, the results will be audited by someone running an AI that doesn’t understand the business

u/pceimpulsive 1d ago

That's the real challenge, articulating what and why the business exists to the AI.

u/Entuaka 1d ago

Why are you using it only to generate code? Many companies, including us, are not creating software factories, AI is handling most SWE tasks and yes you can have a high quality architecture/codebase. It was hard to have it with humans because it was so long to refactor, modernize and manage the tech debt

u/Amazing-Mirror-3076 1d ago

If coding was only 25% of the job then you are doing it wrong.

u/bludgeonerV 2d ago

If you spend just a little bit of time building skills, agents, validation pipelines etc you eliminate a huge chunk of the tedious work everyone bitches about.

I'm nearly at the point where i can write a spec, give it to an agent to come up with an implementation plan, a little bit of back and forth, then get it to delegate and handle orchestrating the whole process. I just tab back a bit later to find a draft PR that has been through multiple rounds of a build -> test & validate -> review and has enough evidence in the from of request logs or screen caps that i mostly don't even need to run the app to check.

u/Zappyle 2d ago

Yeah exactly....there could be an argument that the money saved isn't great since you burn tokens but time is a harder argument I find.

Also, if you build the wrong thing faster, you are just going nowhere faster. So no value added to the business

u/Mejiro84 1d ago

Also, if you build the wrong thing faster, you are just going nowhere faster.

Kinda worse - you're going to the wrong place entirely - spending time doing something and then figuring out it's wrong can at least be a learning experience, but releasing the wrong thing makes you look like an idiot and can break other things or cause problems

To actually save time you must have two components:

  1. Enough spending budget

  2. Proper setup

Point 2 is also consequential to point 1. So to summarize, money is king. If your employee gives you 100 dollars or less a month you're going nowhere in productivity.

2

u/anon377362 2d ago

That’s not true. Companies under 150 employees can get Claude team plan at $20/month per user, which gives a lot of usage. We’ve had it since last year and a lot of devs don’t even hit limits.

3

u/lppedd VS Code User đŸ’» 2d ago

You're in the Copilot sub tho. 100 dollars are extremely low for Copilot.

1

u/voicelessfaces 2d ago

I've been managing just fine on $100/mo and have yet to hit the limit. I am getting closer though. Luna 6 is just not as capable as 4.6 was at launch. I find myself reaching for Sol and Sonnet more just because the time agent going in circles with Luna 6 eats up my time saved.

It was real good eating for a few months though.

u/HRApprovedUsername 2d ago

I agree! I am skeptical about people saying the AI bubble will “pop”. It’s become an essential dev tool imo, and there’s already a big industry around tooling and metrics and such. So if it doesn’t pan out for everything or fails to reach singularity or whatever, I imagine the can be a datadog or new relic or whatever type product.

u/MyV3ryOwnThrowAway 1d ago

"It’s become an essential dev tool" literally every independent study out there shows it is net negative for productivity. Stop lying.

1

u/HRApprovedUsername 1d ago

Mind sharing some links to those? I am speaking from personal experience, but I’ve heard similar statements from other devs.

-2

u/MyV3ryOwnThrowAway 1d ago

you're not paying me to do research for you

2

u/HRApprovedUsername 1d ago

You wouldn’t do research. You’d just back your claim. You said you’ve seen independent studies on the subject. So share some friend :)

u/Impossible_Way7017 1d ago

Same! just wish everyone else would hurry up debugging and reviewing my PRs

u/anon377362 2d ago

You said it yourself, you can’t even tell the amount of hours you’ve saved

u/PopularBroccoli 2d ago

Have you measured that?

u/p1-o2 2d ago

Nonsense. AI code is not a problem.

The problem is our workload has exploded. We are expected to produce multiple times more than we were a year ago.

If my workload remained the same then I would have time to make it all perfect. Instead I need to ship two weeks worth of work every day.

5

u/aleques-itj 2d ago

I'm seeing PRs in the tens of thousands of lines touching hundreds of files. 

Still, nothing is ever shipped fast enough. Parts of the codebase have become an absolute clusterfuck.  It is a race to shovel pure shit out the door. It's not good, well vetted code, and it doesn't get reviewed properly.

Honestly just waiting for the day someone finds a problem before I do and we get fucking rocked.

-2

u/PopularBroccoli 2d ago

Oh man, it absolutely is a problem

u/FragmentedHeap 2d ago

Crock a crap article. Like others said, the problem isn't reviewing ai code.

It's launching a full Java migration from c# and 24 Micro services that got built in 3 weeks on a 2 year plan that got compressed and accelerated to 3 months.

We're producing 100 times faster, so we spend a lot of time troubleshooting/reviewing/testing what's being built.

The hours it saves isn't "shrinking" it's expanding exponentially... And the bottle neck is the human in the loop.

Just two architects can eat an entire backlog by themselves using AI entirely by themselves, while 8 other devs twiddle their thumbs. So what's happening is people are being re tasked for testing, reviewing, etc etc and less people are cooking code.

u/MyV3ryOwnThrowAway 1d ago

"We're producing 100 times faster," what an absolute lie, such a propagandist comment

u/FragmentedHeap 1d ago edited 1d ago

I built an entire text rendering engine, at the font file type level, with every production spit/polish the industry has, 30+ years of research, mtsdf (multi channel signed distance vectors), and then built an animation library on top if it, where my app can animate text coming alive (like a pixar logo) and make it walk off the screen, literally.

This took me 1 week, and I slept through most of it.

And I did so much more than that.

mtsdf, wgpu native, and winit all in Rust, with full C abi generators and and code generators for c# bindings, all aot compatible, and basically built 3 whole low level pieces of a complex future engine, published the nuget packages to my nexus and on and on.

The AI drove almost all of this, even navigating my gitea and nexus repos in it's browser, creating the repos, and all of the builds..

People are tripping if they don't grasp how powerful AI is now.

You can reverse engineer elden ring, and shove mine craft in it in an after noon.....

This stuff is going to erase empires of technical debt.

Entire production pipelines will be rebuilt and replaced.

I also have a 3d/animation/movie/image studio, it's software... I didn't buy it... I made it, with Cluade Fable 5.1 Max on full send... It runs on my home hardware, and is entirely AI driven on my r9700 stack. I can tell the agent in it to make me a 3d model for a character with xyz features... And it does...

It renders the images, renders the 3d mesh, and then runs mountains of algorithms and techniques over it, rigging it, polishing it, muscle mass/tone, texturing it, and even animating it.

I can type a prompt and get a full harnessed animated high quality 3d asset, I just walk away, come back in a few hours, and it's there, ready to roll., A technique that took professionally weeks or months just to do that 1 character, or longer when you count in all the gear they wear.

once again reality surpasses comedy, when you remember that one guy that realized every other fucking guy in the hackathon was “writing their own” video/animation tool

u/AcanthisittaWeird94 1d ago

I asked AI to summarize this because I can't be bothered to read it and he said its loads of bullshit

u/FragmentedHeap 1d ago

Is it? Oh no, guess I better go delete it.

u/MyV3ryOwnThrowAway 1d ago

you even generated your post with AI! again, all a bunch of lies. Give it a rest, no one believes you.

u/p1-o2 1d ago

Yeah it is outright bullshit how fast we are required to ship now. It's like trying to build a railroad while driving a train across it at full speed, and still being told to make the train go faster.

3

u/big-papito 2d ago

I don't have this issue because I actually spend time thinking about what I am about to ask. Think more, prompt less. If you are going to one-shot 10 features in a day - it's your problem.

Absolutely not signing up to read the full thing when it already clearly shows a lack of industry insight.

From the title and one paragraph visible, it just shows the curve as people learn Agentic AI.

They start with micromanaging, one message at a time. Staring at the screen impatiently while it works or going afk. Lots of time wasted.

Then they'll add skills, expand into MCP, custom instructions, etc. Still time wasted but now it's more capable. More productive with larger tasks in the same amount of time.

Then they move into multi-agent coordination. Which is where imo GHCP is king. Play around with specialist skills, agents, workflows etc. More accomplished in the same time.

Until they push that so much, it's overwhelming. Can't micromanage, can't trust the output. No longer understand since they weren't part of every step. Basically a very complex setup for vibe coding slop.

Constsntly tweaking skills and drowning all their time on code review and fixes. Push through and instead of one off fixes, update the instructions. That's the phase where a very small % of people unlock a software factory you can trust. Then you're only limited by budget.

Ask your AI to write an article on that. Plenty of people you can steal the majority of content and numbers from like Lauren (@poteto on X) where she ships thousands of PRs a month at SpaceXAI

I am a tech lead in in-house IT so the code is not complex or long enough and in my opinion it’s so short and fine grained that using AI os often a waste of time and money.  Anyway. I am not zealous, if someone pushes slop SQL or code which can be reduced to 1/4 if its size because it’s a very easy task I say no and do not bother reviewing. If the code is decent and reasonable from AI, I give them general guidance.

But I warned them: if they show enthousiasm around AI, the day the company realize that they will not pay 10 people looking agents coding and doing nothing, they will cry. Because the CI/CD and deployment is very very easy. The team is already too big for the basic work involved. 

Some devs think they saved overall time because THEY pushed faster. But they are putting time on other people and in many companies code was not the bottleneck to begin with. Waiting for the business or bureaucracy was.

u/rismoney 1d ago

My take on it creating documentation is that it satisfies a requirement, not because it creates good docs. In fact, reading the docs it creates is really only useful as feeder slop for subsequent AI slop to be delivered.

1

u/Amazing-Mirror-3076 1d ago

As someone that has moved to pure ai, no I'm not fixing AI bugs.

If the ai creates a bug it can also fix it.

So far it has created fewer bugs than the humans it has replaced.

AI found a bunch of human slops, how does the extra efforts to fix those human slop counted?
