To be fair, DOCSIS 4 uses tk be called something stupid like “DOCSIS 3.1 full duplex” so a lot of areas reporting 3.1 may actually be running 4.
I personally would get a modem with DOCSIS 4 if I had to buy a new one. Replacing WiFi is quite cheap and if access points get flaky there’s always ethernet, but I would get the most up to date stuff on the upstream side just in case the ISP decides to upgrade their network.
DOCSIS 3.0 is a 2006 spec that provides less than a tenth of the bandwidth of DOCSIS 4.0. With the way channels are redistributed, you may not even get more than 100mbps/10mbps if you plug in your DOCSIS 3.0 modem, no matter what your subscription may be, depending on how your ISP deals with old hardware.
The cable frequency spectrum is shared with everyone else, and your ISP isn’t slowing everyone down to make your hardware work, so you’re pushed into thin channels with limited bandwidth that others can use to pull 10gbps down and 6gbps up while your modem will struggle to get any decent speeds.
In theory your ISP could be tolerant to old modems and redistribute their channels such that you’re getting the full speed, but that does mean your entire area gets a lower combined total network speed when people do buy newer hardware. Older modems waste network bandwidth so in congested areas the other side may allocate fewer channels to them.
The latency did improve significantly between 3.0 and 4.0 (ten years of development will do that) but it probably won’t be your biggest problem.
As for the WiFi, I’m still on 802.11ac and I don’t really care that it can only do 520mbps down on my devices. There are some latency advantages to newer WiFi as well but they’re pretty inconsequential if you don’t replace your old modem.
As with so many things, you can give it a go and see if it works. If your performance is not sufficient (or your ISP doesn’t even let your modem connect) you may need to invest in a newer modem.
Newer DOCSIS standards allow for using more frequencies for both upload and download as well as newer techniques. If some frequencies on a network are reserved for 3.1, the frequency space for 3.0 will go down and so will your performance. The frequency space that used to provide 125mbps can now provide someone else with several hundreds of megabits, so you get kicked down to 75mbps for everyone else’s benefit.
DOCSIS 3.0 came out in 2006 and 3.1 in 2013, and 3.1 has already been succeeded by 4.0 in 2017.
The PS3 has a really weird CPU/GPU design that makes it challenging to emulate with any reasonable performance. The same was true for the PS2, which is why a console that old still has to rely on hacks and workarounds to gain any decent performance even on desktop, but the PS3 is a good bit faster and a decent chunk weirder. It also has better copy protection, though I’m sure that has been cracked by now.
I don’t really see what that has to do with the feasibility of writing a new browser engine or the development status of either browser engine, but yeah, it was pretty silly of him to get dragged into an argument over that.
Andreas Kling wrote a lot of Ladybird himself. It’s not finished yet, and it’s turned into a big community project with full time employees now, but with some experience building browsers, the modern spec evidently makes it quite a reasonable task to build a web engine. There are a lot of IDL files and whatnot to parse and process documents and the rendering algorithms are almost all laid out in the spec these days.
I tried Servo last month and I must say that after what I’ve seen Ladybird do, I was kind of disappointed. I don’t think release is very close based on the problems I’ve encountered.

Obviously China’s meddling with academic discourse is troubling, but what universities accept busts for random political activists? I don’t think I’ve ever seen any bust in universities that weren’t of people of great importance to the university itself.
I also completely get universities not wanting to deal with the anger and outrage of nationalist Chinese expats. They can get real angry when you go against Chinese propaganda, probably a result of many years of brainwashing by the Chinese government in their youth. It just takes one weirdo to deface a statue and suddenly you’re in the middle of a massive controversy and need to either file charges (and deal with angry Chinese people) or not (and deal with angry people opposing China’s dictatorial regime).
I’m anti-CCP but that doesn’t mean I’ll accept a bust it a Chinese human rights activist.
