A tech demo shows off the usual tech things.

Then I'm going to jump to a link.

Using the usual tech devices.

We have a plane device called our mouse.

Doing the usual tech productivity tasks.

Now we're connected audio.

You can see my work. You can point at it.

And I can see your face and we can talk.

Except it's 1968, and it's going to set the computing agenda

for the next half century, then almost immediately be ignored.

The mother of all demos on no a little more.

Get it wherever you get your podcasts.

Imagine sweeping through green fields.

Floating five feet above ground.

Sun on your face as you slide by,

on track to your destination.

Not a car in the world.

As you simply lean back.

And before you know it, you're there.

This is how travel should feel.

And on our trains, it does.

Avanti West Coast.
