That’s not quite true. If you look at what Bill Atkinson did with the innovations on the first Macintosh, comparing it to Xerox Alto won’t hold up. Of course they got a first general idea that an interface to a computer could be more than just a command line interface, but the Macintosh is to the Alto what a modern machine gun ist to throwing stones. The principle is the same in the sense that you somehow get a projectile to travel the distance to your enemy beyond your reach to hit him, but that’s about all there is in similarities. On the Alto, the windows couldn’t even overlap… Not to smaller what the people at Xerox Parc did, but the Macintosh Team and specifically Atkinson went way beyond anything that existed before.
