Imagine there is no YT, no Twitter/X, no Facebook, no Netflix, no Amazon, no Apple, no Google to to search the Web, no chatGPT. Imagine there is no TikTok either (even though it’s not US). Just imagine there is no ‘giant’ tech from anywhere owning any app or service that millions if not billions of people are willing to use.
A world without any of those giant (US) tech companies and services that many of us take for granted.
In that world, what would you use the Internet for? How would you use it? And how much time do you think you would spend online, compared to now?
(my own answer in the comments)
OP only listed consumer services, not the infrastructure side. I completely agree with you that if we would take that part into consideration then … Not a lot in the beginning. And in the end because the whole financial sector is also dependent on various US companies and their online services to process most payments … Shit. I don’t know which other critical infrastructures would break because stuff behind the curtain disappeared.

That said if it’s really only “what I as consumer use” then things would look different - even though it all comes down to the details. I.e. no smartphone would be a nuisance … unless Linux phones count.
