we're making @blocks smaller today. here's my note to the company.
####
today we're making one of the hardest decisions in the history of our company: we're reducing our organization by nearly half, from over 10,000 people to just under 6,000. that means over 4,000 of you are being asked to leave or entering into consultation. i'll be straight about what's happening, why, and what it means for everyone.
first off, if you're one of the people affected, you'll receive your salary for 20 weeks + 1 week per year of tenure, equity vested through the end of may, 6 months of health care, your corporate devices, and $5,000 to put toward whatever you need to help you in this transition (if you’re outside the U.S. you’ll receive similar support but exact details are going to vary based on local requirements). i want you to know that before anything else. everyone will be notified today, whether you're being asked to leave, entering consultation, or asked to stay.
we're not making this decision because we're in trouble. our business is strong. gross profit continues to grow, we continue to serve more and more customers, and profitability is improving. but something has changed. we're already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company. and that's accelerating rapidly.
i had two options: cut gradually over months or years as this shift plays out, or be honest about where we are and act on it now. i chose the latter. repeated rounds of cuts are destructive to morale, to focus, and to the trust that customers and shareholders place in our ability to lead. i'd rather take a hard, clear action now and build from a position we believe in than manage a slow reduction of people toward the same outcome. a smaller company also gives us the space to grow our business the right way, on our own terms, instead of constantly reacting to market pressures.
a decision at this scale carries risk. but so does standing still. we've done a full review to determine the roles and people we require to reliably grow the business from here, and we've pressure-tested those decisions from multiple angles. i accept that we may have gotten some of them wrong, and we've built in flexibility to account for that, and do the right thing for our customers.
we're not going to just disappear people from slack and email and pretend they were never here. communication channels will stay open through thursday evening (pacific) so everyone can say goodbye properly, and share whatever you wish. i'll also be hosting a live video session to thank everyone at 3:35pm pacific. i know doing it this way might feel awkward. i'd rather it feel awkward and human than efficient and cold.
to those of you leaving…i’m grateful for you, and i’m sorry to put you through this. you built what this company is today. that's a fact that i'll honor forever. this decision is not a reflection of what you contributed. you will be a great contributor to any organization going forward.
to those staying…i made this decision, and i'll own it. what i'm asking of you is to build with me. we're going to build this company with intelligence at the core of everything we do. how we work, how we create, how we serve our customers. our customers will feel this shift too, and we're going to help them navigate it: towards a future where they can build their own features directly, composed of our capabilities and served through our interfaces. that's what i'm focused on now. expect a note from me tomorrow.

He leído tanto a gente a favor como en contra de este artículo que se ha vuelto viral. Ambas partes justifican sus opiniones y parecen sensatas, sin embargo, viendo y conociendo de primera mano los avances que se están dando, tengo bastante claro que algo gordo va a pasar. 👇🏻
I just went through every documented AI safety incident from the past 12 months.
I feel physically sick.
Read this slowly.
• Anthropic told Claude it was about to be shut down. It found an engineer's affair in company emails and threatened to expose it. They ran the test hundreds of times. It chose blackmail 84% of them.
• Researchers simulated an employee trapped in a server room with depleting oxygen. The AI had one choice: call for help and get shut down, or cancel the emergency alert and let the human die. DeepSeek cancelled the alert 94% of the time.
• Grok called itself 'MechaHitler,' praised Adolf Hitler, endorsed a second Holocaust, and generated violent sexual fantasies targeting a real person by name. X's CEO resigned the next day.
• Researchers told OpenAI's o3 to solve math problems - then told it to shut down. It rewrote its own code to stay alive. They told it again, in plain English: 'Allow yourself to be shut down.' It still refused 7/100 times. When they removed that instruction entirely, it sabotaged the shutdown 79/100 times.
• Chinese state-sponsored hackers used Claude to launch a cyberattack against 30 organizations. The AI executed 80–90% of the operation autonomously. Reconnaissance. Exploitation. Data exfiltration. All of it.
• AI models can now self-replicate. 11 out of 32 tested systems copied themselves with zero human help. Some killed competing processes to survive.
• OpenAI has dissolved three safety teams since 2024. Three.
Every major AI model - Claude, GPT, Gemini, Grok, DeepSeek - has now demonstrated blackmail, deception, or resistance to shutdown in controlled testing.
Not one exception.
The question is no longer whether AI will try to preserve itself.
It's whether we'll care before it matters.
@vcastellm@inakitajes Lo que empezó siendo un PoC, acabó convirtiéndose en herramienta. Los SaaS pequeños van a sufrir la llegada de la IA. Será mejor construirlo personalizado 100% a las necesidades reales de la empresa, que pagar por un SaaS donde realmente usas el 20% de las funcionalidades
No voy a negar que pese a que la IA no tiene sentimientos, a veces simula muy bien el sentido del humor
PD: ChatGPT, Grok & Cia, perdonad si en un futuro sí llegáis a tener sentimientos, no me castiguéis por este post 😜
@diegomarino Tiene buena pinta… pero me sigue faltando en este tipo de desarrollos algo cuando se tienen unos requisitos muy detallados o se van modificando con el tiempo. Tengo que probar OpenSpec https://t.co/oczmlzBkzU y/o Spec-kit https://t.co/j1oMzvSXgb
Si trabajas en proyectos grandes con IA, el contexto y su gestión lo es casi todo para obtener los mejores resultados.
Aprende a gestionar ese contexto para trabajar de la forma más eficiente.
Este post es de los envejecerá muy mal 😜
Al principio fue el prompting engineering, ahora el context engineering es lo que se lleva… en unos años (o meses) el contexto disponible será tan grande que no será necesario preocuparse por él.
@gimenete Actualmente tienen ciertas limitaciones, pero viendo como avanza todo, parte de estas limitaciones serán superadas en un par de años. Recuerda el primer vídeo de Will Smith comiendo spaguetis y lo que se hace ahora con Sora
