> And who loves waiting 30 minutes for Steam games to update on a slow connection? Imagine what we could pack on physical media now and mail to your door if that were still the model.

I mean, say what you will about Steam's server bandwidth, it's at least higher bandwidth than the postal service.

No, it's definitely not. The postal service can easily beat any internet service's bandwidth. It might take 5 days to reach you, but if someone sends you a large box full of 20TB hard drives packed with data, there's no way you could download that much data in 5 days over a normal internet connection.

Somewhat dated by the reference to tapes but still true overall:

It's always been true, depending on how you interpret it. At any given point of time over the lifetime of the internet, there was always more bandwidth in packing a car full of the prevailing storage technology than in using the network. Over time, tape/drive capacities have increased, just as network speeds have, but I don't think was ever a point where the network was faster.

Also, it's probably still true, using the latest LTO tapes.

Do any of these theoreticals account for filling the storage media with data at the source, or ingesting it at the destination?

Yes a container of tapes is a lot of data, but how long would that reasonably take to write to tape? How many tape drives could you realistically have attached to the host system ?

I guess you never saw a proper tape library?

· Start with an 80-slot 6U form-factor Base Library Module, and add up to 6 Expansion Library Modules for a total of 560 slots in a 42U rack form factor

· 25.2PB of total maximum compressed capacity with 560 slots and LTO-9 drives

· Performance scaling from 1 to 42 LTO HH Tape Drives and transfer rates of 300 MB/s per LTO-9 Tape Drive.

Does the robot armature in the enclosure swapping tapes around in Schwarzenegger's Eraser count?

Thanks for the example, that is a lot of tape and a lot of throughput.

Heh, I don't even remember that film.

https://www.ibm.com/downloads/cas/JZALEYPD TS4500 data sheet for even more impressive numbers:

- Number of drives ... Up to 128 per library

- Capacity* with 3592 advanced cartridges ... Up to 877.5 PB native

It's especially ludicrous if you contemplate the microSD card. You can theoretically put 10+ exabytes in a car now. Driving that even across the country is like 100 TBps.

But once it gets to your house, it's actually yours. And then you can play it going forward without a service tracking you. Digital ownership is a massive ongoing failure of a marshmallow test.

What is a "marshmallow test"? I've never heard that phrase before?

A psychological study of children if they would take a small but immediate payout versus a larger but delayed payout.

Honestly, I would take the single marshmallow:

I don't actually like marshmallows enough, so I would probably enjoy two marshmallows less than a single one. Definitely less than twice as much as a single one.

And: given that you are in a psychological experiment, who knows what cruel twists of the experiment the scientists are trying to inflict on you? Perhaps they are actually studying how angry you are going to get when they break their promise? Just eat the damn thing, and they'll have a much harder time taking it away from you.

Children, um, don't use this kind of reasoning.

Depends on the exact age, and how much your kid expects to be trolled.

You mean that study, where they forgot to check for affluence?

Depends where you live ;)
