Excuse me but what do you need 10Gbps internet for? What is the use case? I get the cheapest thing that Comcast provides (50Mbps) and it seems to be enough for the 5 of us at home, everybody always streaming, gaming etc. I have an old asus router I got used in 2015 that I repaired with zip ties otherwise it powers off. At work we have 'infinite' internet (on a class A IP block) and I do not feel any difference in browsing or streaming (obviously I do if I need to transfer a file)

The use-case is because it's so cheap, why bother with anything less.

Currently, I can get 1Gbps Internet for $15, while the cheapest package is 200Mbps for $5. I expect they'll offer 10Gbps in my area in the next few years for the same cost as the 1Gbps now.

Still, at that speed, the router CPU can actually become the bottleneck, and OpenWRT currently has pretty poor support for hardware accelerated routing.

I was pretty worried about that, but the machine I got for my OpenWrt router is a Lenovo ThinkCentre Tiny with a Core i3-8100T CPU ($80 used with SSD/RAM etc included), and it's seems like it's way overkill, even at full bore the CPU usage appears to be negligible. Power usage is the same as the ISP router at about 17W idle, 24W routing 10 gbit, and that's with a 10 Gbase-T SFP+.

It helps that with a 10 Gbps pipe you don't need to run any kind of fancy QoS algorithms or anything...

The price is the same as 1 Gbps ($30/mo) and I built the router out of $100 of parts, so it's kind of why not? It's nice when there are 10 GB updates to download, running off-site backups, and I can host whatever stuff I want out of my home instead of paying for a VPS on someone else's machine and worrying if it doesn't have enough RAM or something.
How do you connect your PC to the router?
For a desktop, 10 Gbps PCIe NICs are not expensive, especially if you go for used ones on eBay.

For a laptop, the Thunderbolt adapters are still expensive, but 2.5 Gbit adapters are very cheap if you can handle that limitation.

With "modern" developing you send whole operation systems images back and forth (docker) or you download AI models, statistics, etc that are many hundred GB. It's nice only having to wait seconds rather then hours. A 10Gbe line usually does not mean dedicated 10Gbe internet exchange, it usually means many people are sharing the same 10Gbe line, so you do not always get the full bandwidth.
I pay 22€ per month for a 10Gbit, so I can definitely afford it. Plus very useful for self hosting
