GIGO - very true.
A lot of AI is trained on scanning stuff on the Internet - web pages, forums, news outlets etc. There's a lot of false information out there so how do they determine which is accurate or not.
AI models are now training themselves on each others data since the source data is drying up as people and organisations become aware of what's being grabbed for free and they're starting to put up Paywalls.
Garbage perptuates more garbage.
AI or rather Machine Learning can have some practical benefits but its being pushed down the throats of businesses as a way of becoming more profitable - less people. Some recent reports have said that while the intial use of AI in businesses is saving time for some people - compling reports etc - they are actually spending more time checking and correcting the output of said AI systems 'cos its rubbish.
Its also being pushed on consumers in the hopes that they'll by more stuff or can grab what they're asking it so that they can target ads to you. This was the hope of things like the Amazon Alexi - just ask it to buy this or that. From what I gather this has never taken off and most people seem to use it as an alarm clock, play music or turn the lights on.
