Overview

A TV show about Ivan Sutherland's 1963 MIT thesis software Sketchpad, which ran on the TX-2 computer. It shows a light pen drawing, constraints, snapping, scaling and object-style graphics, foundations of GUIs and CAD.

On Hacker News

HN returns to it as a striking demonstration that core GUI, CAD and constraint-programming ideas existed in the 1960s.

Demo of Ivan Sutherland's 1963 Sketchpad: [VIDEO] It was a drawing app with the following features: Snap to object ("This allows me to be sloppy while I'm drawing and get a precision drawing at the same time"), connected vectors, arcs, alignment with other objects, copying, multiple "files," scaling ("It scales approximately 2 miles in size"), 3D, etc etc It blows me away that this kind of UI was even conceived in the 1960s. It feels like there was a dark ages middle period after then until quite recently.

TL;DR: If you share the sentiment of the parent commentator you may find this wall of text interesting. You might be interested in Alan Kay's "Doing with Images Makes Symbols Pt 1", [LINK] (46:29). This video features excerpts from Ivan Sutherland's Sketchpad demo ( [LINK] , 10:34; [VIDEO] , 19:19) and Douglas Englebart's seminal demonstration ( [LINK] , 34:45). I recommend watching all the videos in full to get a proper sense of context (Alan Kay's excerpts from Douglas's demonstration particularly don't include the bits that explain how the workstation's camera system works, which is important; also, the right audio channel in the Alan Kay video unfortunately seems to be dead, while the other videos are much better). Highlights from Alan Kay's video include (in hi..low precedence) info about the Sketchpad's CPU, which you might want to listen to twice so you don't mishear (8:58), some really depressing acknowledgements (from Alan Kay himself) that Sketchpad was a never-reproduced gem even in the 80s (8:33), Ivan's (quoted) remarks on the features of the Sketchpad system (7:58), and acknowledgement about the lack of ease of use of light pens (7:12). I consider the above videos to be my own personal pinnacle, what I look up to when I think about good computer design. Some may find them depressing for the reasons you've outlined. It's sad that this obscure niche of computing doesn't lend itself to being very actionable in this day and age. There's definitely no comparison in t

I don't know if it's selection/survivor bias, but every time I watch a video about computers from the 60s and 70s, I am amazed how spot on they are with the trajectory of the technology. Take this CAD demo from MIT back in 1963 showing features that I commonly use today: [VIDEO] Then the 80s and 90s rolled in, the concept is computers that entered the mainstream. Imagination got too wild with movies like Electric Dreams (1984). Videos like this make me think that our predictions of AI super intelligence are probably pretty accurate. But just like this machine, in actuality it may look different.
