What first got me thinking was a few posts on Kibkom that appeared to be from members who hadn't posted for a while, and which were quite uncharacteristic of those members' normal writing style, or were about subjects in which they had never previously shown any interest, or displayed any knowledge of. The posts were notably 'Bland' - mostly in the 3rd person, but lately started to use the 1st person.
I wondered just how easy it was to create something like that, so I thought that I'd give it a try using a free AI tool !
I was using my 'phone, so I chose the lowest resolution, chose something simple and used the following text as instructions...
"Make a short instructional video on how to boil an egg"
That was it, just that text and click on 'Enter'.
To my surprise it did just that - and although it's a fairly crap video (& the eggs appear to change colour in each scene

To see the result click here.
Of course it is probably just as easy for the instructions to deliberately create a false scenario - be careful of what you believe!
