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; [this 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 ot

Demo of Ivan Sutherland's 1963 Sketchpad: [this 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.

Here are 2 that he often brings up: Ivan Sutherland's Sketchpad demo - Object oriented graphics using a constraint based system ( [this video] ) Douglas Englebart's demo - too many innovations to list, but includes real time collaboration (he demoed in a convention center while the system ran 30 miles away in his lab, connected by a leased line operating at 1200 baud!). People think he just invented the mouse, but the overarching theme in his work was augmenting human capabilities... [LINK]

I remember reading an article on Source Code In Database back in the early 2000s, and it's been knocking around my brain ever since as something I ponder every couple of years. I just can't shake the feeling that there's the gem of a future paradigm where everyone wonders "why we didn't always do it that way?", but then every time I try to follow those thoughts through to a conclusion, it always feels like it'd just be re-implementing Smalltalk, and then the question is "why isn't Smalltalk more popular?" That said, there's a lot to be said for revisiting old ideas. There was so much interesting research done in the 60s and 70s in all sorts of random directions, maybe because at that time th

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: [this 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.

"You know what makes the rockets fly? Funding." - The Right Stuff. What really made PARC work is that they were funded to develop the future of computing by building machines which were not cost-effective. It was too early in the mid-1970s to develop a commercially viable personal workstation. But it was possible to do it if you didn't have to make it cost-effective. That's what I was told when I got a tour of PARC in 1975. They had the Alto sort of working, (the custom CRT making wasn't going well; the phosphor coating wasn't uniform yet) the first Ethernet up, a disk server, and I think the first Dover laser printer. All that gear cost maybe 10x what the market would pay for it. But that w

There is more to visual programming than simple wire diagrams and "code-blocks-as-visual-blocks": [this video] [LINK] [LINK] [LINK] And yes, this: [LINK] This is not 100% real programming, because it does not include sensors, but you do create constructs that interact with the environment and accomplish goals. It's close enough to show what's possible with certain interfaces. Long-term: [LINK] There have been much fewer resources allocated to the development of these concepts. Mostly for historic reasons. The sad reality is that both critics and proponents of visual programming are often uninformed about prior work, user studies and related research rooted in cognitive and developmental psycholog
