Good USB-C endurance is 10,000 cycles.

Cheap endurance testers for NEMA 5-15P have a counter that goes to 999999. Expensive ones go another digit.

@dashdsrdash @ryanc @nf3xn is that more or less than a standard AC wall socket?

@Zeugs @ryanc @nf3xn

NEMA is the US standard, 5-15P is the 3 conductor 15A plug side that 90% of the appliances you can buy use, 5-15R is the wall outlet side that 90% of the walls will have. The exceptions are mostly 220/240V outlets and plugs for large air conditioners, electric dryers and such.

Very old houses will have ungrounded 2 conductor plugs; some appliances use ungrounded 2 conductor plugs that work in NEMA 5-15R.

I checked the DE standard, and I'm a little surprised to see manufacturers boasting about 20,000 insertion cycle testing for type F / Schuko plugs. I would have guessed 500000 or more.

@dashdsrdash @ryanc @nf3xn
I could imagine that the plugging frequency could differ for USB.
20.000 is a bit more than two 2 plugging cycles per day for 25 years.
If you use it that much you should think about a good durable power converter in the wall.

@Zeugs @ryanc @nf3xn

I don't believe I have any devices which use USB A or C and will last 25 years.

I have several NEMA 5-15P devices that are more than 50 years old and still in reasonable condition...

but in any case, the question is what you should put into your walls. I wouldn't put USB in the wall; as @cstross said, we'll have a new standard every few years.

@dashdsrdash @ryanc @nf3xn @cstross We need the USB forever* standard.
*Support 50 years

USB 1.1 came out 25 years ago. Extrapolating linearly for the next 50 years, we can expect USB 12 to carry roughly 50 Tbit/sec of data and provide up to 10kW of power on demand.

@Zeugs @dashdsrdash @ryanc @nf3xn

@cstross @dashdsrdash @ryanc @nf3xn If this forecast is right we would have to rewire everything. 3.6kw max for most households. Also the cable must be very much thicker if they stay with 5 volts. Results in 2.000 ampere.

Will we need the bandwidth... We will see. But with Moore's law ending this could be a bit too much to compute.

@Zeugs @dashdsrdash @ryanc @nf3xn This is a classic example of why linear extrapolation usually fails!

(10kW is more than enough power to run every appliance in a house except the heating/air conditioning. And 100 Tbit/sec is probably excessive by a similar margin. Look back 50 years before USB and we didn’t even have/need data cabling in the modern sense … it was 1943 and 50 baud Telex over PSTN was the new hotness!)
