We are now seeing the limits of everything, USB2/3, Gb network (pushing beyond increases complexity to a ridicoulus amount), Gflops/W (2 is CPU peak for electronic transistors) and persistence (the most durable drives where made 10 years ago on 50nm). So now we know that one man can build, host and improve/maintain a product himself with the entire earths population as customers. This is a short window, before thermodynamics takes charge and ruin the prospects, enjoy it while it lasts! The first one to do Minecraft without hiring anyone or selling it wins. :P

In a few years, 2.5Gbps networking is likely to be where 1Gbps networking was not that long ago. What was once niche and expensive will be $20/port very soon, then $10, then $7...

  See I don't think so, because of the physical limits and energy. I think both are peaking at the same time because while you might be able to invent new physics they are only executable in an environment of energy abundance, and peak energy happened 10 years ago. Try getting 1Gb/s to work without going crazy first! ;)

    802.3ab 1000BASE-T works over all of the most common Ethernet cables and structured wiring I've thrown at it, even wiring that probably fails to meet even the loose Cat5 spec. I've not had any experiences being made crazy by it in the last decade. Some of the very old gear had interoperability issues, wouldn't auto-negotiate, etc, but that's often the case on any new "standard" tech. Nowadays, you can take the random $15 adapter, $2 cable, and $20 switch and expect it's all going to "just work" at gigabit speeds.

      What router do you use?
      - sokoloff 6y ago
        My router is an Edgerouter-X SFP, but that is only the gateway from the local network to the Internet, not the main switch. The main switching is done by a mix of Ubiquiti 8-port PoE switches and a Mikrotik central switch.

        And you can push 1Gb/s reliably over that?
        sokoloff 6y ago
        I can push 1Gpbs everywhere on the local net. I can pull 265Mbps and push 12Mbps from/to the internet, limited by the 250/10Mbps internet plan I bought.

        I think it's my ethernet cables... just ordered cat6 we'll see!

  We have had well working 100 Gbit Ethernet for about 8 years now. It's been trickling down in recent years: https://www.servethehome.com/mellanox-connectx-5-vpi-100gbe-and-edr-ib-review/ https://www.servethehome.com/mellanox-connectx-5-vpi-100gbe-... (meanwhile the high end is at 200G/400G now for nics and switches respectively)

    Sure I was talking for the home... most people can't afford $20.000 routers or fiber. I'm prepared to say that unless they can cram 10Gb/s into existing fiber (without increasing fixed- or energy- costs too much) we're stuck at 1Gb/s... forever!

      Anyone with $40 USD can buy a used 10gb ethernet card and wire it with cat6. I don't know why you think there is some 'limit of thermodynamics' or that someone needs to 'invent new physics'. Every computer for 15 years has come with a 1gb ethernet port. 2.5gb usb ethernet dongles are $30 USD and can be hooked into a $35 rasberry pi. A 2.5gb switch is around $120. I don't know where you got these ideas, but they wouldn't have made sense two decades ago, let alone today.

        You again? Are you stalking me? Do you know how bad your username is? How hard would it be for me to get you banned? You don't want to see that hard worked 2000+ karma go up in smoke! Because then you cannot downvote.

        If we take a step back, you have said that "we will be on 1gb ethernet forever" "because of the physical limits and energy" and that people will need to "invent new physics they are only executable in an environment of energy abundance". I then point out that 2.5gb pcie cards cost $20, usb dongles cost $30 and a switch costs $120 (with everything using the power of a few light bulbs at most). Instead of confronting this or saying something that makes sense, you say that I'm stalking you, call my user name 'bad', then say that you are going to 'get me banned'. Did I miss anything?
