I think you're highlighting two different problems here.
I agree that Gen Z and younger are, on average, far worse at basic computer skills than many seem to assume. It makes me reflect on my tech-learning throughout my childhood, as a Millennial. I think that part of it is that many erroneously assume that because Gen Z has grown up online, that this will lead to proficiency, but the kind of tech they've been exposed to is largely walled gardens and oversimplified UIs. That assumption of proficiency leads to scenarios where their lack of skill is only discovered when they enter college, or the workplace. I am astounded at the prospect of people not even knowing the difference between "Cut and Paste" and "Copy and Paste". It's grim.
The poor quality of journalism may be linked to this, but I think it's larger than that. It seems like it's not a great time to be a journalist at the moment (my writer friends tell me that increasingly, the only work they're able to find is copy-editing AI shit). Private equity is fucking up so much of the world — journalism included. Polygon is an example of an outlet that was apparently sustainably profitable, before it was sold and experienced mass lay-offs; an individual company's success doesn't matter to the big conglomerate that owns it. I know that other journalistic companies have fallen to the same fate too.
It also seems that tech journalism ends up being especially shit. I didn't start noticing it properly until I watched this podcast episode from "Tech Won't Save Us". The TL;DW of it is that tech journalists like Kara Swisher like to pretend that they speak truth to power, and fire hard-hitting questions at big tech people, when that's patently bullshit and it's clear that they only get the access that they do by playing softball with the powerful. We can't blame a few individuals for the entirety of the tech journalism problem, but I reckon it's a big part of it when so many of the established, big names in this space don't seem interested in actually doing tech journalism (and smaller names who want to ask journalistically interesting questions don't get platforms or access to ask those questions).
Our information ecosystem is not in a great place. I've found it tremendously beneficial to curate the news and information I'm exposed to (praise be RSS), but that has been a gradual process of actively working to notice good journalism in the world and build up my mental "rolodex" of people whose perspectives I trust to be worthwhile (even if I don't necessarily agree with said perspectives). However, this is an area that I care deeply about, and thus it feels worthwhile to spend that energy to curate my infosphere. Most people won't have the inclination or energy to do this work, which is unfortunate.
