So what? Instead of punch card, you now have blu-ray and flash drives - the compression of data has changed, the ideas behind its storage for input not so much. Just the fact that ones and zeros are now represented by tiny black areas on plastic, not paper, does not make a qualitative change.
The qualitative nature of the change is not in the technology or it's underlaying systems. If it were, then there would not be a qualitative change between hand-forged tools (carbon-infused iron heated and battered into shape), and machine-forged tools (carbon-infused iron heated and battered into shape), even though the modern tools might be a hundred thousand times bigger and be ready to use in a tenth the time or less.
The
qualitative change, is in our
relationship to that technology.
...
I've no idea how old you are or aren't. But I actually do (dimly) remember the 1970s, and I remember the 1980s. My first introduction to home video games, was the original
Pong console unit. More to the point: the first personal computer I owned, was a Commodore Business Machines
C-64; I got it for Christmas in 1985 ... I was fourteen years old, and the C64 was an absolutely amazing piece of technology at the time (also, one of
the gifts for the holiday, and gods bless my mother for the scores of hours of overtime she worked, and then tens of hours she spent scouring stores, in order to get it for me).
Now, the C-64 was, by today's standards, a woefully primitive, underpowered, limited-capability machine. No hard drive, no built in nonvolatile memory - there were two options for permanent storage were (a) a
cassette drive, or (b) 5.75" floppy disks. There was no "mouse" or other pointer - though you could use a standard Atari 2600 style one-button joystick for many games. I
think you could connect it to a modem, but I'm not sure that was even possible. Compare that to my current PC, and .... good grief, my
mouse has more computing power (and probably more memory) than the whole C64 did!! The internet - email, Twitter, Facebook, Steam, streaming movies from NetFlix, iTunes (hell, my iPod is a million times the computer my C64 was) ... yeah. The whole adds up to a
strong qualitative change. Because, sure the parts each existed independently in 1985. But they hadn't been put together, and more importantly
had not yet been rendered commercially affordable to the majority of people, until many years later.
To be as succinct as I can: how we
interact with and relate to all those devices and systems, is what has changed. And in sixty years? We are not able to predict, with
any degree, how we will interact with and relate to the technology available to us at that time.
Which is to say: while looking to real life for ideas is all well and good, "it isn't possible because the setting says so"
is also a legitimate response, simply because
doing otherwise might never occur to someone in the setting. After all, how many teenagers right now are perfectly comfortable surfing the web on any number of devices, even circumventing parental control locks or other security measures?
And ... how many of them would know how to use a TELNET client, without looking the instructions up online?

Hell, how many of them would even know what TELNET
is ...?
Now project that forward, to those teenager's
grandchildren in the 2070's.
