The non-determinism is part of the allure of these systems -- they operate like slot machines in a casino. The dopamine hit of getting an output that appears intelligent and the variable rewards keeps us coming back. We down-weight and ignore the bad outputs. I'm not saying these systems aren't useful to a degree, but one should understand the statistical implications on how we are collectively perceiving their usefulness.
The other thing to note is that journalism in the US has gotten really lazy. A lot of the articles you will see in the MSM are based on leaked info and press-releases from PR firms, etc. It's easier to for journalists to regurgitate stories hand-fed to them than doing truly hard and costly investigative work.
