Could this be a case like investment alpha? If you have a real life use case and share it then you could lose the opportunity.

So some "experts" could be staying quiet because they don't have one. But some may stay quiet because they are working on or benefiting from it?

I thought this too initially, however by now I would expect one of those to 'break rank' and actually demonstrate some impressive use case, I've not seen anything in terms of 'fire and forget' agents actually achieving a task of any complexity. I had some success using AutoGPT to do some web scraping and it's ability to use powershell was impressive and powerful, and with no safeguarding somewhat hazardous, however it's unpredictability was intolerable.

They're already very good at pissing off your customers in the "support" section of your website.

people that have stuff working won't be too keen on showing it to you - especially if it is lucrative :)
