You put it jokingly as I understand it but I can tell you that for my garage where I have a IP controlled CNC machine I did upgrade to EtherCon plugs from Neutrik.
I don't know who designed the original RJ45 connector but it sure was not made to last in that environment without decent mechanical decoupling of plug and cable. It is actually toy grade, but it works if you don't touch the cables.
Another thing I have done three years ago is in my home lay a backbone from floor to attick of 10Gb optical cable. I had already three RJ45 cables running and needed another one and than thought enough is enough. The 10Gb switches were on sale back then for $200 a piece and in the meantime my PC and NAS have 10Gb NICS.

Well their like washing machines the volume of production is just completely INSANE, there is no reason not to put a ethernet jack on something or not to own a washing machine if you can possibly own one (who the FUCK goes to a laundry mat where your clothing can get stolen and you need to sit there for a fucking hour guarding shit in a humid lair filled with weirdos wearing over turned dirty wife beaters??)

No matter what processor, chinese resistors, etc you use, you still need to put the same ethernet jack on everything.. so some guy instantly got freaking high on the notion that saving 0.1 cents translates to what, millions? (even if there are billions to be made)

I think extreme mass production causes different psychological response to traditional accounting.

I mean USB is still pretty damn good compared to LAN and Phone. That little plastic tab is just.... ::). I wonder why USB is built so nut and bolts in comparison to the fucking LAN connector though. It boggles the mind.

1 more vote for - Ethernet to Fiber converters .. one one job, we use 100s kilometers - 1000+ runs, in very noisy / dangerous environments .. never ever had
an issue in 20+ yrs. (It's at a shipping port). Converters can be quite cheap, and made up fiber (or terminate your own) .. easy peasy.

SFP ports prefered ;) Try to avoid old school converters if possible.

God damn computer should be grounded through the ethernet. It's clearly all built completely wrong. Our treasure troves of high end test equipment are being compromised by cheap grounding solutions.

The big advantage of Ethernet is the galvanic isolation it provides so unless there is a specific reason to use them, it is better to avoid shielded cables.

I have seen industrial stuff where the RJ45 (and Molex) connectors were inside of a large screw-on connector housings.  Something similar can be used for RJ45s connectors in wash-down and marine environments

I was surprised how inexpensive new network interface cards with SFP ports are but I suggested external Ethernet to fiber bridges because they will work with anything and the cost is comparable anyway.  The difficult part appears to be finding long pre-made fiber cables.
