Speaking of Alan Kay, the operating system of the Xerox Alto was Smalltalk. The GUI that Steve Jobs poorly copied to make the Lisa and then the Macintosh was itself a programming environment. Unfortunately Jobs failed to grasp that or didn't care about giving users control over their computer. In fact, all evidence points to his specifically not wanting users to have any control. So he stole the Alto and crippled it to make the Macintosh.
Probably the closest Apple came to something like the Alto's programmability was #HyperCard. The only mention of Jobs's name on the #HyperCard Wikipedia page is where it talks about how Jobs killed the project BECAUSE HE DIDN'T LIKE SOMEONE WHO WAS WORKING ON IT.
What a fucking asshole.
@freakazoid Oh man I loved Hypercard. Probably wouldn't use it now myself, but I can imagine it would still be a great introduction to programming for many people if it was still around, the same as it was for me back in the day.
@freakazoid Wow. I did not know that. Yeah, Hypercard was extremely powerful back in the day.
