I've been working on a small side project: type-annotationify. Migrate full-fledged TypeScript to type-annotated TypeScript compatible with the type annotations proposal and NodeJS's strip-types.

I really don't want to be vegan.

Because actually I have no problem with killing animals for food - it's just the way of the world.

I don't even really mind torturing animals for food - as long as they're low cognition (fish, insects, etc)

However - I really don't want to participate in the active (often life long) torture of high cognition animals like pigs.

Chickens are pretty dumb, but I'm not down with stuffing them into small cages their whole lives to peck at each other.

Not ok with dairy cow-calf separation.

And the more you look into it, the more you realize that humane sources of meat, dairy, and eggs are VERY hard to come by. Buying the more expensive brand at the grocery store does not imply torture free.

If you're eating bacon, an egg, cheese from a random restaurant - you are participating and enabling animal torture.

These labels "vegan", "vegetarian", "pescatarian" don't work for me. A vegetarian who eats dairy and eggs still participates in torture.

I would lustfully eat a steak that had a good life, or an egg from a non-factory farm.

For all the daily political bullshit that happens - the torture of billions of animals is so rarely discussed.

@robpalmer2 Downgrade for decorators? Seriously? They are finally unflagged in TypeScript and now back to the drawing board? The saga continues

@sebastienlorber Just in time for my 40th birthday! Too bad time is also immutable in real life 😉

@sebastienlorber It's about time btw

@robpalmer2 Why do we care about commonjs in 2026? I know... I know...

@robpalmer2 Imagine the compute cost!! 🤯

[Nico Jansen @_nicojs]

@typescript > strict is now true by default

You should have lead with this. This is huge!! 🎉

@theo Any plans for creating an enterprise offering? That's where the big money is for when this runs out (probably in 2 weeks 😉)
