Re: internet service

I live in the US so it's standard to offer a come-on rate of like $35/month for six months or a year and then the rate jumps to like $85/month (plus fees and taxes taking it to the better part of $100) for some shitty-ass service like 400 Mbps down, 5-10 MBps up cable with the promise of high-split getting installed sometime circa 2032.

 That sounds excessively high by about 2x. In the UK I get around 500MB/s for about £33/pcm after a bit of haggling. I used to have 150MB/s for £30/pcm. Korea is the place to be for truly hyperfast BB.

Different US markets have different "norms".  I know folks who have had Gbe
at $20 for YEARS!  (fiber to subscriber).  Here, one can readily choose
between DSL, cable, microwave, etc.  I can get higher bandwidth on my
phone than we have for home service.
But, there are also caveats with many providers.  E.g., I can go
anywhere and "do" anything with my current provider.  Others may throttle
connections or block certain domains.
I DL about 20GB daily.  EVERY day.  Because the machine can do it without
supervision (i.e., without MY involvement), why would I need anything
faster than that?  So I could archive even MORE stuff??  I'm just
finishing 12TB of rainbow tables...
For us, reliability is important.  We don't lose our service when
a contractor cuts the CATV feed up the block.  Or, when the telco
technician jiggles OUR pairs while servicing someone else.  Or,
when the power fails.  etc.
[In power outages, I just keep doing what I'm doing and the
neighbors wonder why there are lights on...]
A movie is maybe 1-3Mbps of bandwidth (SD or HD720) -- assuming an elastic
store.  Ditto interactive audio/video.  If you consider internet service as
part of your ENTERTAINMENT budget, then you may be willing to replace those
1Mb streams with 50X so you can pleasure yourself with that 8K screen.
(Does the STORY change with the screens size or resolution?)
If your alternative for the MANDATORY "big screen experience" is a
movie theatre with $10 bags of popcorn, then spending that on a
high speed link may be a bargain.
Will ALL of the sources you want to access be able to keep the pipe full?
Will you feel cheated if you've paid for bandwidth that you're not able
to use, at the moment?  How happy are you driving your Lamborghini
on city streets?  :>

My tiny rural village is unusual in having full fibre to premises on tap. Neighbouring ones have VDSL or rival microwave peer to peer links.
 Give up on the landline entirely and you can have 1.6GB for £70/pcm

 EE (aka Orange elsewhere) is now a part of BT (as is Plusnet - who are even cheaper but more consumer than business orientated).
 Haggle and you will do better than their first offer price.
