IBM crashes because we’re gonna YOLO a replacement for banking and credit-card back-ends, replacing billions of lines of COBOL with vibe code.

@nlowell @FknHannu @timbray What I want to know is how these models could possibly have been trained on enough COBOL to be even slightly correct. Are there mountains of public repos of COBOL I’m not aware of?

[deadinside@but.still.drinkin.coffee]

@timbray Yes. Let them.

Do. It.

@timbray how many COBOL codebases have good test suites? I suspect none.

How well do LLMs do without tests / types / guardrails?

Best practice AFAIK is to run in parallel with prod. I guess they could try that, but it would take like a monthly billing cycle or a quarter to test one change.

@ibboard @timbray Oh so that's what people meant when they said Artificial Intelligence is just a bunch of IF statements.

if it's able to """"""understand""""" the code
if it's able to maintain it
if it's able to modernize it
if it's able to replace it
if a bunch of other stuff it's not able to do
...
and most important of all

if my grandma had wheels, she would've been a bike.

@timbray I wonder how much of this is "now they are going to have to divert resources to deal with this nonsense" instead of it being a realistic competitor.

Kinda like, this DDoS of management attack will degrade their performance.

vibe trading vs vibe coding 1-0

[jc0f0116@infosec.exchange]

@timbray webdev vibecoders and llm industry have one thing in common: they're both at the very end of a massively complex and fragile network of interdependant components/processes, and have seemingly no understanding of its complexity. that's how you get "we're just going to build a million datacenters in a year and then the agi will just rewrite everything in rust, simple "
