The hard way was beautiful. The hard way is also done. On mastery, grief, and what happens when your hard-won skills become abundant.

People worry to much about being "fair" when allocating resources in a business. Your job is to win, and you don't do that by playing politics and peanut butter spreading your resources around. You do it by doubling what works. - Engineers delivering value from tokens get more tokens, not a spend cap. -Leaders landing outcomes get more teams and better projects, not a carved up team. -AEs closing at higher rates get the best leads, not some randomly assigned roulette. You want to win? Learn to measure what works, then double down.
Every leader we talk to at @cxodev is worried about AI spend right now. Hard caps make the budget math easier, but they also cap your return. Here's what we tell people: - Make sure everyone has spend visibility. You can't optimize what you can't see. - Go talk to your top spenders and find out what's what. Some people have great ideas. Others are being naively wasteful and just need a little education. - Talk to your bottom spenders too. They haven't figured out how to get value out of the compute yet. Why not? - Avoid hard caps. Give more tokens to the people getting actual leverage, not less.

Why does my 11-year-old need IRB approval for testing whether different music affects concentration, but social media companies can A/B test “what if we made everyone 12% more unhinged?” on a billion people?

These guys had engineering jobs. Just sayin'.

The fun ones are 5 figure monthly bills, no one can explain what it does, it's in the "Sacred Cloud Project From The First Days", and middle management is too scared to turn it off and find out.
On my deathbed I'll still not know what this AWS bill is but pay it anyways

Except who is responsible for production.
ai ended so many process debates that have existing among programmers forever

It's an optimistic view that most organizations were successfully following principles like least privilege, well defined interfaces, or minimized surface area. I expect agents, over time, to increase the security posture of most companies. They follow the rules better than most people ever did.
I'm relatively confident in predicting that currently, more major breaches are likely to be the result of AI use by the target, not the attacker. Ransomware actors have been consistently winning for over a decade. They've had so much time to perfect their tradecraft, and non-AI ransomware actors can now blast through entire networks in minutes. It is extremely unlikely that organizational security has, in 4 years, after decades of failure, matured enough that hackers now somehow need AI to win. What has likely happened, though, is that organizations have spent the last 4 years falling over themselves to shove AI into everything, negating longstanding security fundamentals. "only give a user/system the minimum possible access needed to do its job" has become "just give the AI access to everything and give everyone access to the AI". "use processes with well-defined and easily auditable input and output" has become "the AI correctly processes requests all the time, 60 percent of the time" "reduce attack surfaces" is now "every department should be vibe coding. It doesn't matter if you've never coded before and don't understand information security. Just make public-facing dashboards, it'll be fine." I'd say if anything, hackers aren't getting measurably more sophisticated, but the average organization's security posture has gotten exponentially worse.

There's many things that were created to make infra legible to non-infra engineers. Now infra only needs to be legible to agents. This will be simpler in the long run as we converge towards a new stack with less abstractions.
What is the point of Vercel and stuff like that when I can just rent a server and have agents manage and optimize everything for me?

A lot of VC backed companies are well capitalized research projects, not businesses. Nothing wrong with that. Just know which you're joining. And recognize it's really fucking hard to turn a research lab into a business.
Many GTM problems aren't GTM problems. They're "we built something nobody urgently needs" or “we don’t understand our users” problems wearing GTM clothing. I said what I said.

Infra people know many devs don't know where their stuff is hosted either. Innovation is a function of how much you can do without thinking about it. Make the tools good enough people don't have to know where stuff is hosted.
My friend made a really impressive app. It's live and has users. He has no idea where it's hosted.

Many companies would do a lot better if they could intuit this.

AI as a grounding wire is a great take. When we can get a fast, machine driven, emotionless, exhaustive second opinion on anything, it really changes the baseline expectation for what you trust. We don't have to use status as a shortcut anymore.
People who have been in research fields develop a felt sense that most "research" (in almost any field that isn't exactingly technical) is research theater, and many superstar careers enjoy star status not because of a unique connection to the truth but because of a unique connection with an audience. No one really has the time or stature to, from a position of objectivity and trust, bring popular researchers to heel. But it will get increasingly hard to hide from serious critique. The machines can do critique now, at the level of depth and rigor previously only possible for the academically deranged. We're going to have to revise a lot of what we "know" about the world that isn't really knowledge but is actually just received popular consensus - like floating voltages without grounding wires. The grounding wires are coming.

Biotech X is where you go to offset the AI doom and gloom. @x gods please feed me more of this.
this might be my last normal tweet before biotech goes vertical i'm not a whistleblower. I don't work at Lilly, Novo or any of the big labs but there is a massive shift happening in human biology right now. it's sitting in press releases and almost nobody reads them the last 6 months alone: - a once-daily pill roughly doubled median survival in metastatic pancreatic cancer (13.2 vs 6.6 months) - a one-time gene editing infusion cut hereditary angioedema attacks 87%, and 62% of patients stayed attack-free and off all other prevention for 6 months - a one-time gene edit for cholesterol dropped LDL up to 62%, and it held for over a year - a personalized mrna vaccine beat keytruda alone in a 1,137 patient melanoma phase 3 - retatrutide hit ~28% weight loss in a phase 3 - an ai-designed drug entered phase 3 - a pill that regrows hair passed its second phase 3 - an immunotherapy that could let some rectal cancer patients skip surgery, chemo and radiation just got fda approved - a man lived 271 days off dialysis on a pig kidney - human cells were caught passing chromosome-sized chunks of DNA to their neighbors, and it changes how the neighbors behave we are on the verge of an era where the human body is a software problem and the update cycle gets shorter everyday stick around, it's going to get weird bio/acc

Human relationships are a great way to identify which tasks can be done by agents. 1. is it strictly transactional? ripe for replacement 2. is it primarily relational? agent can't do it The key is the same task can be transactional in one context, and relational in another.
I was listening to Peter Thiel’s interview with Walter Isaacson last night. Isaacson asks something like, “What do you think will matter most post SI” Thiel takes his characteristic 30 second pause, thinks about it, and responds, “Human Relationships”.

My bet: Defensive swarms will be required for anyone running their own software.
As someone who builds what I think is considered a “defensive swarm” product, a big part of my bet is that Nikesh (Palo Alto Networks CEO) is wrong. The token economics are increasingly in our favor. You really can throw tokens at logs.

Seems like we've forgetten the "service" part of SaaS is what matters. No one was ever paying you for access to your beautiful UX. They were paying you because your pricing was cheaper than their cost to build + run it. Build is 1000x cheaper (not free), so that's changed build vs buy calculations. Maintenance & reliability remain a painful headache people will pay you to deal with. Critical 0 day vulnerabilities are just going to get worse (hello eMudhra certs and PHP RCE from just the past few days). Failover and redundancy are hard to architect (looking at you Revolut bank). Companies that already have to handle maintenance and reliability are less inclined to buy your software. The incremental cost to add one more internal app is lower than ever with material upside if they can retain specialized knowledge and data for their business.
The dirty secret of SAAS is that subscription pricing allows you to keep charging customers who aren't really using the product. The downside of this is that when your subscriptions finally churn, it's a *lagging indicator* of your business failing. I strongly suspect that there are many, many "dead men walking" now in SAAS, both AI-native and traditional: businesses where the financials may still look fine -- just a quarter or two of stagnant growth, margins are still great, maybe there's an AI narrative going forward, etc. but the *product* is losing utilization and they will lose every single customer to {{AI-native competitor, possibly the big labs themselves}} as the customers encounter those solutions. Those customers become dormant users, but the subscriptions still run for the while. The actual revenue churn only occurs months or quarters later when the question of "is anyone still using this? do we need to keep paying for this?" is finally answered with a "no" rather than an "i'm not sure".

I'm reminded daily that choosing your problem is also choosing your competition. I'm the undisputed market leader in finding things my children can't locate. My entire competitive advantage is actually looking.

I bet a lot of future AWS/GCP/Azure/OCI spend will tilt towards the foundation labs. And this "magic compute" idea is a great example of why. Every lab is going to optimize its models for its own managed version of magic compute. It's basically the equivalent of AWS optimizing for and subsidizing Lambda. imo the big labs need to yank the next generation of programmers into their ecosystems and reallocate cloud dollars into their managed services to survive. Those are massively profitable markets. there's a huge market opening up of people who want to deploy/run software but REALLY don't want to understand cloud compute concepts. The labs already have to build out a lot of the expertise needed to run datacenters. They already have to secure large compute contracts. They're already building highly optimized hardware. Feels pretty natural that their fully integrated SW/HW stack will work best with their managed "magic compute" offering. Will be interesting to see how this evolves.
seems obvious to everyone around me that sandboxes are on their way out. we hear too many stories about reliability, capacity, broken sandboxes that need manual intervention -- plus they are way too expensive for what they provide. the future for agents? workspaces. your agent doesn't need a computer. it needs a place to store it's context, and the *tools* to manipulate that context each turn. we're in the very early stages of the AI era. the simplest version of this pattern is just handing each agent a time-multiplexed VM, since that's the only thing that we have at hand right now. over the next 12 months, you're going to see a rapid shift away from this model and towards what i call the "magic compute box". rather than giving an agent a VM, you give it a set of tools (could be "bash", "python", "js", "read_file", "write_file") -- and you send those commands to a magic service in the cloud that manages to run them for you -- using the cheapest technology available (just-bash, wasm, or even Linux if really required) for each command invcation. your agent doesn't want a computer that it can set a desktop background for, it wants a place where it can fire off an unlimited number of tool calls and have it update the context correctly.

Cloudflare and Coreweave should really be one business.
