Lex is God.
This is one of the most significant advances for mankind!!!
Alpha fold team interview podcast please!!!!!’
The next step is going to take the 3D structure and adding chemical and physical activity in different environmental scenarios!
One step closer to Terminator. Thanks everyone for your hard work.

12:20 "Because the protein structure gives us the protein function…"
As a student of protein engineering, I have to say this is half true and half not true. It would be true for things like antigens or structural proteins, but not necessarily true for enzymes. You would have to run many simulations on all likely chemical substrates to actually learn something about function that wasn't already available from the original sequence and the related sequences. One amino acid change can improve/decrease the efficiency of an enzyme by 1000X for a given substrate and catalytic condition (temperature, pH, ect..). But that kind of stuff is already being done on the structures obtained by the previously very slow and expensive process of X-ray crystallography, so now we can use these structures as inputs.
Incredible, thank you Lex!
(hopefully) Helpful feedback: too much speculation up front on other things, get right into alphafold!
MAKE MORE!!!
so cool we could design proteins to do basically anything
when biology combines with computer sciences it's really crazyyyy
I enormously appreciate you and your content, Lex! I just wanted to say that I think a more politically correct way would be to say "there are 10^80 atoms in the observable universe" vs "there are 10^80 atoms in the universe". 🧐😂
Good deal ty
this was great lex!
AlphaGo AI beats human players
"Why are they wasting their time and money playing games instead of developing cure for cancer!?!"
AlphaFold solves protein folding
"crickets…"
just googled some diseases that result from misfolded proteins, here is the google result: "Protein misfolding is believed to be the primary cause of Alzheimer's disease, Parkinson's disease, Huntington's disease, Creutzfeldt-Jakob disease, cystic fibrosis, Gaucher's disease and many other degenerative and neurodegenerative disorders." This could be a step towards ending Alzheimers!!!!
Well it probably won't be solved perfectly until quantum computig enters the game.
Which Biotech stocks would you buy in light of this breakthrough? Which companies are well-positioned to make quick profits out of this breakthrough? Large pharma companies or unknown startups?
I’d say this is LEXI
This is a simulation right?
And the goal would bassically just be to accept peace, both with all other humans as well as the planet itself, all of its animals, a renewable energy source so that we can have energy free for everyone…
Wonder why we didn't do
that sooner..? 🏭🏦…
I still think we can win.

"Very overcaffeinated organ that's producing this very video" 😂😂😂
Thank you so much Lex. You have explained this extremely well thank you
4:45 While I don't at all disagree with what you say I have to say I think its only a matter of time before certain AI will be implemented to help people and be optimized for their specific functions and they obviously work in the stock market now etc.
Would u please consider having ur father back on to discuss China new “artificial sun”…HL-2M Tomahawk reactor they fired up this week??
This video is a great overview. I hope to see your coverage when the paper comes out. Thank you.
When will they release the code? Cause I heard an opinion that
1) Black box solution is useless because you can not check if it's true. So if you have to every time recheck AlphaFold output with traditional methods what's the point of that?
2) Following from the 1st. It doesn't explain HOW protein folds.
3) It might be trained specifically to solve CASP-like problems and will fail on real ones.
And all of the above sound reasonable.
Transformation attention engines: How much of a change in DeepMind's programming is refocusing the learning algorithms of the last success (AlphaGO ?) to a new dataset and learning goal?
Or, as the developer's library of block functions improve, is DeepMind moving towards General AI capabilities of being able to learn, how to learn?
Sell out, satanic nonsense.
Thank you for everything you do Lex!
Yes, this tyoe if video is awesome, make more! Also, you should have George Church, or Aubrey de Grey on the podcast
