Internet Is Fun 
The technology that actually changed your daily internet use mostly arrived without a launch event. It was infrastructure, defaults and small interface decisions, and by the time anyone noticed, the habit had already formed.
Infinite scroll removed the stopping point
Pagination used to end. You reached the bottom, and a decision appeared: click for page two, or stop. Infinite scroll deleted that decision.
It is a tiny interface change with an outsized effect, because the natural end of a session disappeared with it. Nothing about the content got more compelling. The exit just stopped being offered.
Autoplay changed what a video is
Once the next thing starts by itself, watching becomes the default state and stopping becomes the action you have to take. That inverts the relationship: you are no longer choosing each video, you are declining to interrupt a stream.
Search became an answer engine
Search used to hand you a list of places to go. Increasingly it hands you the answer directly, which is genuinely convenient and has a real cost: you visit fewer actual websites.
That has knock-on effects for anyone who publishes. Fewer visits means less reason to maintain a site, which means fewer independent sites, which means the answers have fewer sources to draw on. It is a slow loop and we are some way into it.
Apps replaced the open web, then partly gave it back
For roughly a decade the trend was to move everything into apps, each one a walled garden with its own account and its own rules. That has softened. Browsers got faster, web apps got better, and a lot of what needed an app in 2014 now works fine in a tab.
The web did not win outright, but it stopped losing.
Recommendation replaced subscription
The older model was subscription: you chose sources and saw what they published. The newer one is recommendation: a system infers what you will engage with.
Recommendation is better at surprising you and much worse at being reliable. If you have ever failed to find something you definitely saw last week, that is the trade in action. It is also why the old discovery methods are worth relearning.
The pattern
None of these were sold as changes to your behaviour. They were framed as convenience, and they were convenient. The behaviour change came along attached.
Worth knowing, mostly so you can tell which of your habits you actually chose. If you want a sense of which internet era formed yours, there is a quiz for that, and more in AI & Tech.
