In ten years time YouTube will be entirely inaccessible from the browser as the iPad kids generation are used to doomscrolling the tablet app and Google feels confident enough to cut off the aging demographic.
This is obviously not plausible. They're never going to shut off browser access on people's laptops. Watching YT at work is a major thing. I have to assume you're joking, but I honestly can't figure out what point you're even trying to make. Do it think it's surprising that an ad-supported site has anti-scraping/anti-downloading mechanisms? YouTube isn't a charity, it's not Wikipedia.
I was reading a study recently that claimed Gen Z is the first generation where tech literacy has actually dropped. And I don’t blame them! When you don’t have to troubleshoot things and most of your technology “just works“ out the box compared to 20 or even 10 years ago, then you just don’t need to know how to work under the hood as much and you don’t need a fully fledged PC. You can simply download an app and generally it will just take care of whatever it is you need with a few more taps. Similar to how I am pretty worthless when it comes to working on a car vs my parents generation could all change their own oil and work on a carburetor (part of this is also technology has gotten more complicated and locked down, including cars, but you get my point).
The point of all this is I could definitely see a world where using a desktop/laptop computer starts becoming a more fringe choice or specific to certain industries. Or perhaps they become strictly “work” tools for heavy lifting while mobile devices are for everything else. In that world many companies will simply go “well over 90% of our users are only using the app and the desktop has become a pain in the ass to support as it continues to trend downwards so…why bother?”
Who knows the future? Some new piece of hardware could come out in 10 years and all of this becomes irrelevant. But I could see a world where devices in our hands are the norm and the large device on the desk becomes more of a thing of the past for a larger percentage of the population.
