Saša Jurić is fantastic at condensing lots of information in a 1 hour talk without losing the audience, he gave another great talk this year called Parsing from first principles (https://www.youtube.com/watch?v=xNzoerDljjo).
“React to the future” by Jordan Walke. Why ReasonML is a logical extension of ReactJS’ programming paradigm. https://youtu.be/5fG_lyNuEAw
“Typing the untyped: soundness in gradual type systems” by Ben Weissmann. The trade offs that various gradual type systems make based on their language constraints. https://youtu.be/uJHD2xyv7xo
“Let’s program like it’s 1999” by Lee Byron. How the mutual feedback loop of abstraction, syntax and mental model drives the evolution of web technologies. https://youtu.be/vG8WpLr6y_U
There was quite a bit of time in between the invention of implementation inheritance and the whole "prefer composition to inheritance". It's quite possible OOP became popular due to implementation inheritance then realized it was dumb.
Agree. The talk is very thin on the real differences between OOP and functional languages.
This old comment  points out that functional languages tend to make it far harder to reason about low-level details, for instance.
Personally I think it's more fundamental, and isn't about any such technical limitations. People have a strong intuition for time, which is emphasised in imperative languages (including OOP), which have the semicolon operator or an implicit equivalent. The concepts at play in the fundamentals of Haskell are simply harder, and 'more mathematical', than the sequenced mutation-based statements of imperative/OOP languages.
This talk is very good. It's one of the few talks that I've overheard classmates talk about. It not only asks a question a lot of people exposed to functional programming at university asks, but also answers it in a way where you learn more about the world of programming and programming languages than you expected.
All talks will be livestreamed (and usually become available for download one day later) at .
Also, rest of his talks are also fascinating:
Took 2 courses under him @UMass. An extremely demanding professor, but each of his classes are an absolute delight.
Talk about Svelte v3 and the (possible) future of frontend frameworks

Excellent informative and hilarious talk about his (at-the-time) new scientific hypothesis to explain the end of the Bronze Age ca. 1200 BC.
Multiple civilizations collapsed within a few decades of each other with the ability to read, write and make high buildings being lost all across the Eastern Mediterranean simultaneously. The Bronze Age is magical and interesting of itself, the talk gives a great introduction as to why we know much more about it than we think.. definitely recommended.
Duration ~1 hour (feels like 20 minutes)
I learned so much for this talk. I had a much different idea of the point of iterating rapidly and what product-market fit meant before this video.
1. The Church-Turing Thesis and Physics
2. The Limits of Efficient Computation
3. The Quest for Quantum Computational Supremacy
I don't know if Bryan Cantrill has done any speeches this year, whenever i see some speech featuring him on youtube I watch it regardless of the year.
That man is a gold mine. And I always learn something interesting.
new startup with Brian, jess frazzle and Steve tuck.
I've already heard some fantastic stories from their guests, particularly the guy who used to work at intel.

Brendan presents news tools and new flows that can be used to analyse performance bottlenecks.
He get you in the demo and you stay to receive more and more information. It seems to be a talk that he has been improving over the years. Totally worth your time seen it.
Composing music functionally, aka functional composition :)
Also, after seeing what kind of magic he can do with the right representation, I wondered how many "business domain" models I know could be expressed with models that "click" in the same way (i.e. are expressed by simple concepts and compose as well).
I feel as if many of us often give up way too early in the search for good models for our data. Myself included, of course.
Shameless plug since I'm the speaker. The reason I'm posting this in "best talks of 2019" is not because I think it was a good talk (my ego isn't that big yet) but because I think very few talks exist on the subject of Behavioral Programming, and it's a subject I'm hoping can get more attention.
This  talk about building worlds in Blender by Ian Hubert.

not, the survival of the fittest.
the extension of generosity of surplus
to other members in the ecological community
to build biodiversity
not the individual that survives
but the community that survives
Crazy Code, Crazy Coders
I purchased his book, Crashed: How a Decade of Financial Crises Changed the World without really knowing much about it (or him) and found it to be a great, semi-technical story about the financial crisis (and its politics) from the global perspective.
Good talk behind the reason for the T2 chip and some other Apple security stuff
Because, sometimes you need to worry less about the gritty details of the tech and take a step back and look at the bigger picture.
James Powell never disappoints :)
Basically made an awesome list of applications written in Python(now is 380+), then answered the frequently asked questions by the community about how to develops applications using Python.
The data is also available.
Most interesting development for me in 2019 were the ongoing political realignments - the right no longer sees the free market as compatible with their social values.
Bruce Sterling has been around in the intersection of art and technology since the dawn of the internet. His gothic, villain, medival high tech scifi world are a hilarious inspiration.
Lastly, covers the US/China “trade war”.
Fascinating and very well structured talk, revealing the hidden (to me) forces behind economic structures and decisions.
His recent Twitter posts suggest that economic inequality in the US can be achieved through taxing the rich, which while not an original thought, seems sensible.
