Never saw this before, how cool. It makes you think about the current state of software: the main difference is that we can do the same things as is seen here, but in the browser. Apart from that our day-to-day software might even be less advanced. Apps like Notion come to mind as a modern day equivalent. The only thing is that this is more than 30 years ago!
If you have the time, grab Sheepshaver and boot up the last version of Hypercard. You will see that it did a lot of things that a browser simply cannot. For example, you can copy a button from anywhere and paste it into your own stack using copy/paste. Think of what it takes to do that on the web!
