> The high expense of 10gig is, in part, because it isn't widely necessary and the people buying it are willing to pay extra.

I think the price has more to do with where you live and how the market is structured than how necessary it is. In Japan where there is competition between ISPs, I pay about $40/mo for 10Gbps.

Routers have also come down in price to where they are pretty affordable for consumers. I use a Ubiquiti Cloud Gateway Fiber [1] which has three 10Gbs ports (two SPF+, one 10GbE) for $279. A TP-Link router [2] with an upstream 10GbE port and 2.5GbE LAN ports and Wi-Fi 7 is about $140. 2.5 GbE NICs have become cheap and ubiquitous and could commonly be found on $150 mini pcs (before memory and SSD prices went crazy).

Yeah it's more than more than most people need, but I definitely appreciate having the increased speed when downloading 50GB games, uploading 200GB files to YouTube, or backing up files to the cloud. I've probably never maxed out the full 10Gbps, but exceeding 1Gbps is pretty easy in relatively common use cases.

Depends a lot on your work type and your prior exposure. If you only work "locally" and upload/download rarely, you may be way less demanding of your network than if you actually do distributed work with remote storage, high-bandwidth communicating tasks, etc.

Over 20 years ago, I was used to having 1g LAN for basic workstations and laptops in an office setting and probably 10-20g uplink from the building (shared by hundreds of staff). I also used 1g at home for my very small LAN between laptop, desktop, and SAN functions. But, my home ISP links were often terrible, such as 128k ADSL or even just a tethered GPRS phone at some points.

You end up with entirely different work styles when you have these different resource constraints.

I put 5Gbit internet into my home (fiber) to build my startup. I'm processing terabytes of data. I have over 100TB of storage in my basement. I can regularly saturate my internet connection. That said, I remember well when a 1Gbit connection provided enough bandwidth for a 500-person call center for daily workloads (back about 10 years ago).

I have it more for the fast nas access and being able to treat nas disks as more or less the same performance as if they were directly sata in my machine. Significantly less so about the external network aspect.

1Gb Internet service seems low these days, much less 1Gb LAN. I have 3Gb Google Fiber service and actually get 2+ for individual downloads from some internet services like Steam. Even at 2Gb it's annoying to wait tens of minutes for 100+ GiB games to download. If I go on vacation I come home with 10s of GiBs of photos and videos on multiple devices that start syncing with cloud storage.

During the day I need to pull large data files from the work VPN so it's nice that that can happen at full speed even when Steam and movie streaming are also at full throttle. Combine that with backups and moving various files back and forth to my NAS and I'm very happy to have 10Gb local wiring.
