I think I've been lucky to get the speeds I have. I remember when I first moved to where I live now with my now wife, she had ADSLMax BT Broadband that synced at 8Mbps, but did not go above 3Mbps. BT were adamant this was "just how fast it went". Naturally unhappy with this response, I moved us to Sky where ADSL2+ was available and we got the full 16Mbps that Sky did at the time. I noticed the green cabinet being dropped in early 2012, and am pretty sure I was probably one of the first people on it. 40/2 and it was a really nice boost from 16. Similarly, first to jump on Sky Fibre Unlimited Pro (I think it was called) in July that year and got moved to an 80/20 profile where I think I started out at 73/20. Now that was great, and by that point we'd had decent 802.11n routers so WiFi worked pretty well everywhere and that was that.
However, as has always been the case, I think the use cases for internet access have changed as the internet has evolved over the past 20 years. Having seen dialup->1Mbps ADSL - now that was simply mindblowing because of the "always on" ability and not having to worry about the phone bill. It's like we take these massive leaps from access speed in front of what the internet is capable of.
I think this time, moving from FTTC to FTTP however, we're entering an entirely new paradigm in access technology. Companies are selling "1Gbps services" but the reality is that Wi-Fi is now ubiquitous amongst the general population, and we get annoyed if we don't get the speed promised. Well, for 99.999% of cases with FTTP, the speed delivered to the router is exactly as promised.
1Gbps means you are probably quicker than things on the internet, I often see single threaded direct downloads in Windows only really go at 100-300Mbps. On the flip side this does mean I am no longer saturating my connection with a single download. Now, not so bad in my house as it's just two of us, and my wife isn't also downloading all the time, she's a fairly light user of the internet, so no big deal, but I'd imagine in busy households, the extra bandwidth will let everyone share with less complaint.
Get's even more interesting when you've got 10Gbps connectivity and Wi-Fi7 - Have tested both in the lab (and 25Gbps, but that's for another day) and whilst we had 3.9Gbps out of a OnePlus 11 phone, some trickery was needed to get there.
I run a steam cache at home for when I was using FTTC and Starlink as I tend to game on a few different machines - above 3Gbps and you are CPU limited - even on a 12 core Ryzen 9!
