Things like this are easy to say when you're the employer, you get to select whatever portion of resumes you want with impunity. As the employee that needs a job to keep on living people tend to do anything they can to get their foot in the door. Hence, this is why resume inflation/copying known good resumes was a thing long before LLMs.

Now, if you're a smaller business, you'll very likely notice these effects and the number of resumes is rather small. But in larger businesses they may get thousands, tens of thousands of resumes, and the vast majority of them are culled by automatic processes and people that have no understanding of the real requirements of these jobs and said 'generic' resume might just allow you to get past said filter better than randomly stating who you are.

"putting your art, writing, expression out to be judged by others is an act of bravery as much as talent, and a lot of people lack braver-y. Sorry to say it but if you need your work to be polished and beyond reproach, that's a determination and character problem, not a skill problem."

Or maybe you know enough people are just generally mean and jerk enough that you don't want to listen to their silly criticism and over-the-topness. And there really isn't any benefit to you for putting it out there.

Perhaps if employers were better at identifying people's skills from their CVs, they wouldn't need to use AI to rewrite them. A lot of the time, it feels like if your profile doesn't match 100% of the keywords in the job description, it's just automatically denied on sight, even if you've clearly got the ability to do the job. Heck, a lot of the time these systems can't identify synonyms or recognise when a skill is blatantly obvious from the description (like knowledge of Git meaning they have knowledge of Version Control).

People are relying on these things because hiring systems are rejecting their applications otherwise.

As for the AI generated portfolios and Git repos... that's not quite the same thing, but even then it's because expectations for employees seem to have become rather ridiculous in recent years. It's apparently not enough that you've got experience working in a field, you're expected to be obsessed with it in your free time too, and document every little thing you ever worked on online for all and sundry to see.

I don't like this. I'm here to do a job for money. This just pressures me to present myself as whimsical and interesting in an HR-friendly way. I feel for the regular dudes who feel like they have to dance for HR people who spend too much time on LinkedIn.

The irony is that AI makes it easier than ever to show what you can do, but people are using it to hide who they are.
