1) The prompts/pipelines portain to proprietary IP that may or may not be allowed to be shown publically.
2) The prompts/pipelines are boring and/or embarrassing and showing them will dispel the myth that agentic coding is this mysterious magical process and open the people up to dunking.
For example in the case of #2, I recently published the prompts I used to create a terminal MIDI mixer (https://github.com/minimaxir/miditui/blob/main/agent_notes/P...) in the interest of transparency, but those prompts correctly indicate that I barely had an idea how MIDI mixing works and in hindsight I was surprised I didn't get harrassed for it. Given the contentious climate, I'm uncertain how often I will be open-sourcing my prompts going forward.
There's also the lessons on the recent shitstorms in the gaming industry, with Sandfall about Expedition 33's use of GenAI and Larian's comments on GenAI with concept art, where both received massive backlash because they were transparent in interviews about how GenAI was (inconsequentially) used. The most likely consequence of those incidents is that game developers are less likely on their development pipelines.
If your hand is good, throw it down and let the haters weep. If you scared to show your cards, you don't have a good hand and you're bluffing.
In a lesser example, a week ago a Rust developer on Bluesky tried to set up a "Tainted Slopware" list of OSS which used AI, but the criteria for inclusion was as simple as "they accepted an AI-generated PR" and "the software can set up a MCP server." It received some traction but eventually imploded, partially due to the fact that the Linux kernel would be considered slopware due to that criteria.
"Some people expressed disappointment about a thing I think is silly" is literally the center square on the gamer outrage bingo card lol. Same with "someone made a list that I think is kind of stupid".
And again, so what? Why should you care? Again, if you feel that insecure about it, it's you and your work that's the problem, not the haters who are always going to exist. Have the courage of your own convictions or maybe admit that it isn't that strong of a conviction lol.
Pulling this victim-blaming sentence out of context to show how ridiculous it is.
Given this stance, I think GPs reasoning for not publicly bragging about using AI makes perfect sense.
Why paint a target on your back? Why acquiesce to "show us your AI" just to be mobbed by haters?
Fuck that, let them express their frustrations elsewhere.
What I'm saying is that _feeling_ of insecurity doesn't come from haters, because haters gonna hate, it's a sign that _your_ work might not be as good as you think it is, and you don't feel that you can stand behind it.
Also, managing public expectations and messaging is a thing professionals in many industries do all the time. It's not even particularly difficult, you just hear about it when it's bungled.
EDIT: To clarify, as a SWE, my work is available to anyone at the company. Any engineer I work can see what I've done, and the public sees it too, they just don't know about it, because if I screw up, the company will take the blame for it. You get very very very very used to critique in this role and taking responsibility for what you make and making the case for your technical solution.
