Future breaking news: Cisco hardware used in massive botnet attack.

Ignore, for a second, the use of AI here.

How huge a screw up is it just to send a guy off to work on a project alone for 2 years. Can you imagine the amount of time that should be spent in code reviews looking at something someone has spent a full 2 years on? You're now going to be asking senior devs to spend months of their lives doing nothing but code reviews. And, if you skip the code reviews that's suicide.

We all know that in 2 years Cisco is still going to be using their legacy codebase. There's not a chance in hell this will work. Just announcing this like it is a sane thing to do advertises their dysfunction.

It's possible that he will find some low-hanging fruit and be able to rewrite some library code. But, really, when rewriting something old and bloated, the main thing you can do to add value is to remove code. And, AI agents are famous for their ability to generate vast amounts of code, not to get rid of it.

The absolute best case here is that this guy wastes 2 years of his life, and Cisco has some kind of deal where these "unlimited AI tokens" come at some fixed price so that this project costs Cisco only $1m or so. Then, the project's a failure, they only lose a bit of money, and they can maybe learn from the experience. But, do you really make an announcement about a project that's only going to run you $1m in costs? I doubt it. This is probably Cisco setting fire to $50m or more. And, given that they announced the project like it was a good idea, can they afford to just admit it failed? With that kind of sunk cost, they're probably going to feel a lot of pressure to achieve something positive with the stunt... so something here is going to be integrated into their codebase.

... and suddenly, overnight, claude or whatever will have very detailed, intricate knowledge around Cisco's hardware, almost like it's regurgitating internal documentation. Hm.

Don't worry, guys. I am sure he adds "make no mistakes" to every prompt. No review necessary, push straight to prod.

What happens if the price of those tokens suddenly skyrockets because the provider now knows your entire operation is relying on this one guy vibing?

I don't know... Have you provisioned Cisco equipment before? It feels like the quality can only go up.

(But no, obviously this will end terribly unless they're incredibly careful. It's possible, but unlikely.)

"Claude, rewrite all of these repos but better"

Done, and done!

This should be entertaining

So they're replacing battle-tested unmaintainable old code written by humans with bad unreleased unmaintainable new code written by ai.

Both are unmaintainable. What's the punch line?? Is this not the onion?

Cisco just handed a 27 year old unlimited AI tokens and the keys to 98% of its codebase. Somewhere, a senior engineer is quietly updating their resume. Rewriting code is easy. Discovering why that horrifying 1998 workaround exists is the actual final boss.

Holy shit, this really seems like something that you shouldn’t announce publicly

That is peak level CEO magic thinking

Well this is concerning. Our entire network runs Cisco.

I think the 24 months is the scariest part. If the Eng is starting now & has 24 months, that’s one can of worms.

If they’ve been rewriting over the last 2 years… AI has changed a lot for code writing in that time... 😬

"Welcome back to another episode of the premier game-show of the 21st century: 'What Could Possibly Go Wrong?' Man, do we have a great one for you guys tonight..."

Legacy code is still around for a reason. It’s not usually just a matter of refactoring it, but the business logic tied around it all.

Good luck lmao. Cisco will be underwater in years if they actually commit to this.

had founded a translation startup

Doesn't Cisco know any networking and firmware experts, with extensive legacy code knowledge, who could vibe code through a well thought out plan?

Hey I'm rooting for the guy. If in two years they release this mostly generated code it should be entirely public domain. Public domain slop is better for me then hostage making spyware.

lol

When I was 27 I’d been coding for 15 years, so age alone shouldn’t be the red flag.

What is going to be a pop problem is the insane number of Chesterton fences stomped down that fuck everything over, or things that look like they can be optimized out or use cases you don’t think actually happen.

See rust core utils for an example of extremely well trodden and well reviewed software that ran into these issues for years. Not that it’s a bad effort, it’s an inherently hard task.

Leave two bullshitters in a room and they come up with this lol

There's no way "Paddy" explains the disastrous results to Patel, who's gonna be real mad at the end of these 24 months, if not sooner, wondering where all the money went and where's the ROI.

Truly the rule of dumb.

Isn’t Cisco gear running a lot of the Internet backbone? This should be interesting…

Well, let's see in what new and interesting ways Cisco software can break. Not that they needed help but it'll be fun to see this unfold.

time to buy cisco stock, just remember to dump in about 2 months when this inevitably goes to shit

Time to short Cisco.

How does one managed to earn this level of trust?

Oh this is bound to end well.

Legacy code is better than vibe code code....

What's he gonna do for the rest of the 23 months?

what could go wrong

There’s no way one person can understand all the things that all the code at Cisco does even at a high level.

You can't fix IOS, Cisco. All that god awful patch work is technical debt that can never be saved. RIP

So the other 2% are all the hardcoded admin credentials I suppose.
