People also got lazy, why bother hosting your own website when you can just upload to Instagram ?
Why maintain bookmarks when you can follow others?
I don’t think we can blame all of the current state of things on “attention grabbers”. Consumers and creators are also partly the issue.
Why bother changing your car oil when you can take it to the service?
Why bother cooking your own meal when you can just go to the restaurant?
Why bother sewing your own dress when you can just go to the mall?
It's not lazyness, it's convenience. Internet just got mainstream and popular, so people lacking time, interest or skills to create their own websites just use pre-built solutions. It's how everything works in real life.
They don't lack any of time or skills. Take the example of websites of local sport clubs: they all had a proper website with all info and news and stuff. Now they haven't any more, they've changed to a shitty Facebook page with everything mixed together into an incredible mess. (By the way, the traditional website is typically still running fine without maintenance, it just hasn't been updated since around 2015-2017.)
I don't think the people from your small town random sport club, who built and ran the site in the 2000s, had special computers skills or time compared to those of today.
I think this “everyone got lazy” is overblown. Yes some folks are lazy, but they were the folks that used Microsoft Frontpage in 1998 :)
The restaurant does not take away the meal from you after you ordered it, because you are not woke enough.
If you buy a dress, you own it.
On Wordpress, Instagram and YouTube you are just a sharecropper with no rights.
I understand the sentiment, but convenience isn’t always the right thing for us.
It happens when a service get too many users, and it ends up like everything else.
Instagram & facebook are a global scale economic mammoth that subsist on promoting the dynamics you are lamenting don't exist.
Maybe people have a lazy tendency. They can use that to build structure. Once it exists, it also becomes true that if you want people to read your post, it needs to be on instagram, fb or whatnot. If you want people to see your video, it needs to be released on youtube.
Even if people were willing to host their own video, youtube has all the viewers. A viewer/user on a centralised platform is worth more (economically) than elsewhere.
So we wanted a website. Previously I had already "made websites" by saving as HTML in Word, so let's go! But I figured we need to do better than Word, because Word's output was messy and often rendered broken in browsers, so I found an HTML tutorial and I managed to hand build a simple site, with the aid of shareware Windows software for creating button images with cheesy fonts and another one to generate thumbnails of images etc. We then wanted a discussion board, so I figured out how to install phpBB.
I had no knowledgeable geeks to guide me in real life but through these experiences I picked up real programming skills in my teens, JavaScript, CSS, HTML and PHP (and probably actively contributed to PHP's meme reputation as a tool of kids and dilettantes). A few years later I learned Python to mod games. I learned to put computers together and had a rough but cloudy idea of how it all worked. I liked it and went on to study CS, where I first learned C and C++ and Java and a proper theoretical foundation which I also liked because I liked math.
It was only in my mid twenties that I started to look into Linux. All my peers had been using Windows my whole life and I was a bit afraid of becoming a full on social outcast Linux nerd. But then in my twenties I lost my urge to conform so hard and overall came to like Linux. Overall I'm now quite comfortable with the command line, shell scripting and so on.
My point is, I was nothing special of a geek and had no geek peers in my teens but through necessity I picked up geek skills to make a website, to fix computers, to pirate stuff, to mod games etc., which led me down the path of pursuing CS as a career. I know I wouldn't have enjoyed it if it was presented to me as some gameified app to learn programming with some upbeat cheerful mentor. I loved it for the exploration, for the "nobody told you you could or should do this but can you make it work?".
Would I have become a CS person in today's climate where we would have just made a Facebook group to upload our class trip photos without learning any HTML? Perhaps, maybe through game modding. But do kids today have the same chances to mod games with all the DRM and always-online monitoring software? Would I have learned about TCP/IP if everything worked out of the box? Although I'd love to say I learned it all out of intellectual curiosity, in the moment I picked up these skills because I had something concrete in mind that I wanted to make, and learning these was the only way. If there was and easier way, I would have been lazy and in turn perhaps miss out on all the wonders of this field.
On the other hand there's just so much helpful material out there today, you can buy electronics hobby kits on the cheap, Raspberry Pi, all kinds of programming tutorial.
Any input from today's teens/early twenties how this works today? How and why do kids pick up tech skills nowadays that everything is so convenient and streamlined to consumption and locked down for inspection?
My passion for computer hardware (and to a lesser extent software) comes purely from my childhood, I'd say. It had a great effect, and actually led me to many paths I wouldn't have taken otherwise. Also, I gained non-tech skills as well, like my handling of the English language, for instance.
I can't answer your question, since I have had quite a different experience, but the reason my acquaintances are picking up tech skills is because it's the future and it's where the money is, or because their parents told them to. This is really unfortunate because they don't actually bother picking up any tech skills at all unless they absolutely need it (which is very rare in 2020 due to how everything is so convenient / available). However, I am from a poor country, so I am not the best person to answer this.
Personally, I prefer the old internet. Not only due to what I mentioned, but also because the current internet is just full of messed up things like the current state of social media (really, HN is the only one I tolerate) and how rooted it has become, or how people in general became more afraid of expressing themselves on the internet, and so much more.
Most of them seemed to have taken CS classes in high school and enjoyed it reasonably enough or have had CS recommended to them as a major since you could easily get a job in it (like the other reply to your comment suggested).
On the other hand, my interest in CS and programming was a lot more old school. I got on the internet for the first time in the mid 2000s and learned to make basic websites for my hobby and then JS, PHP, MySQL to make them interactive. I'm not sure I would've followed the career path I'm in now if I'd been born 5-10 years later. The epicenter of my hobby moved to FB/Discord/Instagram/Youtube and if I were growing up now I think I would've tried to share my hobby through those platforms and therefore never gotten into what I did now. I'm lucky I was born the time I am and thanks for an interesting question to think about!
