To be fair. In Star Trek they're not really using a GUI like we use a GUI today. They are using a high level AI to take voice commands. And they use the visuals to confirm. That is not what gooies are today
Yeah but Scotty knows all the keyboard shortcuts for a classic Mac which means that they still somehow exist in the future. So…we can safely assume that shortcuts as they exist now are present in the same mapping as they are in the future which means we have no excuse not to memorize them. Not just copy and paste but opening and maximizing windows via shortcut. It is apparently something that still needs to be done in the future.
Scotty's special. The rest of the future people are confusing each other to death on Stack Overflow, which by then has centuries of outdated answers and every possible grammatical question is a duplicate.
Scotty is totally the kind of engineer with a garage full of retro gear he has only to appreciate how things used to be done. He learns how to run a classic Mac for the thrill of archaeological engineering
