About this video

Alan Kay's 2015 talk on the power of simplicity, arguing that systems become simpler by building on more sophisticated fundamental building blocks and that big research horizons drove invention at Xerox PARC. It ranges across computing, tools and scaling software.

Why it appears in the archive

HN repeatedly cites it as a thought-provoking talk on reducing software complexity and on the state of computing research.

Completely unrelated: Alan Kay - the power of simplicity [VIDEO] Easily over of the most thought provoking presentations I have seen recently.

Highly recommend his talk on the power of simplicity. This was one of those lightbulb moments for me when I was a younger programmer: [VIDEO]

I'm not Alan, but I saw one of his talks[1] about how they did invent all those things we're using now, which you are very much referring to. What he said was important was to have a big horizon, at least 10 years. Anything less would not do. Then envision what should be possible in that time. "It would be ridiculous if $X wasn't possible in $Y years" and then backtrack on what would technically be required to make that happen. Rinse repeat. He said that with good company support and a good team, you often found yourself delivering at half that time none the less (but again, you should never constrain yourself to that little, or else you will stress towards performing, instead of thinking properly about the problems needing to be solved). Alan: Hope I didn't butcher your message too much :) [1] I think it might be this one, but I honestly haven't checked. See it anyway. It's a good talk. [VIDEO]

I've seen him give this great talk before, but IMO the delivery this time feels rushed and a bit disjointed. That said, the last few minutes summarize his powerful "Gretzky Game" idea so succinctly that they're worth the price of admission alone. I would recommend watching the last 18 seconds of this version (starting at [LINK] ), internalizing the Gretzky Game slide on the screen, backing it up and watching the fuller explanation in the preceding ~3 minutes (starting at 54:18, [LINK] ), and then finally watching a different, more expansive version of the talk like this one, given at Qualcomm: [VIDEO] . Oddly specific advice, I know, but hopefully helpful to somebody.

Not sure which generation you're in and which generation you'd (relatively) consider Alan Key in, but here is a much more principled approach to what the OP is trying to do: [VIDEO] The TLDW is that Kay thinks we haven't discovered all the fundamental rules of computing, a la Maxwells Equations for physics. If you are able to figure these out, you can substantially cut down your accidental complexity. FWIW, my unscientific view is that achieving simplicity is really hard and doesn't scale people-wise. Instead of C99 without a bunch of stuff, I'd probably use Scheme to create very dense (lots of bespoke abstractions and idioms) but simple software. That approach works reasonably well, but try onboarding a new developer!

In his "Power of Simplicity"[1] talk, Alan Kay had a great illustration of this specific phenomenon using astronomy: Before Johannes Kepler had the insight of describing the orbits of the planets with ellipsis, peoples were using the (conceptually simpler) circles which didn't completely match the observed movement of celestial body such as Mars, thus resulted in complicated circle-within-circles orbits to try to model reality. By introducing a more complex basic shape (ellipsis instead of circle) which happened to match the underlying reality more, the overall description of orbits got greatly simplified. It's a phenomenon I've seen a few time in my career so far: that while often there's complex code because there are actually complex hedge case to handle (essential complexity), sometime it's really because the data structure used to model the thing you're handling is slightly missing the mark, making things fit almost-but-not-quite, and many operation done around to handle data can be greatly simplified (if not avoided altogether) by changing the underlying data-structure. (Also, Alan Kay apparently did another talk called "Is it really complex, or did we just make it complicated"[2] that seems pertinent to the thread, though I haven't watch it yet) [1] [VIDEO] [2] [LINK]

Check this video running in another thread. This a known Alan Kay talk, he did it already a few times. [VIDEO] As an example of the type of research being done, you must be willing to build something that will be considered commodity in 15 years time at today's price. You won't get there with basic income.
