Excited to participate in the Vibe-a-thon at PS/NExT in two weeks! #PSNext2026

@NathanS64855891 Getting AI to operate on ASTs would be amazing. Not sure how we get the training data for that, but it’s clearly where things should be headed.

[Philip Su @philipsu]

We need to stop doing code reviews. AI code generation volumes currently make code reviews impractical, but they'll soon be impracticable, and ultimately downright irresponsible.

"Lights-out codebases," where no human ever sees the code, will need to be the norm. When I was at Meta many years ago, it wasn't uncommon to spend perhaps 1+ hours a day reviewing others' code. With AI easily generating 5-20x that volume, it should be obvious that our future can't possibly require human code reviews before merging PRs.

Perhaps more controversial — but equally obvious to me — is my claim we'll one day be appalled to learn that any mission-critical software we rely on (e.g. cloud platforms, Stripe, etc) allows human intervention of any kind in its code production.

It's time to go lights-out. You can embrace this proactively by vectoring your engineering methodology toward this inevitable future, or be overrun by the deluge that eventually forces your process into acquiescence.

I’d like to think I was always the hero of my entire bed, but with this purchase, I’m now sure.

@dmwlff @Meta @reactjs Working with you on Chat was one of the best experiences in my career. I remember doubting your assertion that a thumbs-up reply would be useful — and boy was I wrong.

@ID_AA_Carmack Agreed. 0.1 increments is the secret. In 5 years I've brought it up to 3.5x. At first, jokes weren't funny and nothing was emotionally resonant. Now, facts & feels are all normal, and 2x seems like someone's trolling me.

[Philip Su @philipsu]

@_paulshen Whoa - this is really amazing! Will give it a spin, and also chat with others about it!

So proud of my son Caleb, 16, who just launched Terminal Knockback, a platform fighter placing Zelda BoTW characters in the Smash Bros universe — with final smashes, training mode for combo practice, and adjustable-difficulty AI. https://t.co/fVmHApxWbc

With over 2000 assets drawn pixel-by-pixel, it maxes out Scratch's 5MB Javascript code limit. Without a doubt one of the most full-featured games on the platform. Play in Chrome or FF: https://t.co/tpcjqIIXlQ. See full code: https://t.co/71RfLKa4EH.

@gbarkerZ @graham_gunning @blindsunflowerb Works for me now as well!

[Philip Su @philipsu]

@gbarkerZ Unfortunately crashes for me upon launch on iPhone 8+. Let me know if there are other things I can do to help debug!

@Sottorete The various roles are monitored differently. In Ship Dock, you’re rated by your hand scanner on the number of boxes you load every hour.

@Author_Caleb_C @peaksalvation My first job in the US was below minimum wage. I'd like to begin the discussion with your first job, then perhaps we can start from a place of less instant-judgement first.

[Philip Su @philipsu]

I've been enjoying this podcast, which is like an audio version of Black Mirror. Today's episode mentions the @peaksalvation podcast, which I'm grateful for!

"There's an app. It tells you the best response in each situation - job interviews, dates, where to live, what to eat, how to make love, how to raise your kids. It WORKS. It gives you the optimal answer every time. Heaven or hell?" - @pmarca to @FistedFoucault

Ep 24 out now.

@Scramazon @aj_was_annoying @GoodPoliticGuy It's not the article title - what you read is what the OP on Reddit chose, quite unfortunately, to call his post.

[Philip Su @philipsu]

@SoDRalin Is your take that no one who can get a higher paying job can, without harsh judgment, work a warehouse? What about volunteering - would you judge that less, or is that a "safari" as well? If you aren't doing the highest-paying job you can right now, are you also on safari?

Buying every Meta employee a coffee was one of the most memorable experiences of my career. It’s not often that you can make a connection with relative strangers by giving them something with no strings attached.

[Rahul Pandey (joinTaro.com) @rpandey1234]

. @philipsu was an eng director at Facebook

On his last day in 2018, he bought free coffee for 1000s of employees across the world -- just show any barista your badge and order anything you want.

Free coffee, no strings attached.
