Forge
Every development organisation can now learn at AI speed
Chapters I and II were about what AI can do for the services themselves. But every development organisation, whatever programme it runs, also has an enormous opportunity to move faster with AI: to run its core operations better, and to learn faster what works.
Unfortunately, very few people in development have been close to how fast things are now moving, and I think that's why our level of ambition is lower than it could be.
The opportunity
In development, execution matters just as much as intervention. The same teaching method can do a great deal or almost nothing, depending on who runs it and how.
The Uttarakhand and Bihar effects are not statistically significant. The states started from different levels, so each bar shows what that approach achieved where it ran.
So the best programmes keep getting better the way good products do. They try versions, measure each, and keep what works. I've been very aware when writing these essays of the (true) adage: technology is not a silver bullet. One day, walking through the park, I realised: technology is not a silver bullet, but experimentation is a forge.
AI-enabled iteration could make in-category variation so large that intervention type becomes far less informative. … What predicts impact may no longer be labels like ‘AI tutoring’, but an organization’s ability to rapidly iterate.
AI is making that forge much, much cheaper and faster, and I think that within a year it'll run much of the loop itself: building the versions, measuring them and keeping what works. We know that teams that build with it can ship far more, with fewer mistakes, because a few development organisations already work this way.

This isn't only true for digital products. It's just as true for the ordinary systems that run a programme, and at most organisations that's where the impact is, rather than a flashy AI strategy: proven programmes going bigger and more effective by doing the boring stuff better and faster. As one example, a highly effective education programme is commissioning software to assemble its lesson plans. Its RFP follows what used to be a normal timeline for a build like that, and the gap vs. what's now possible leaves half a year of impact (and, I suspect, around $100k) on the table.
Our ambition is lower than it could be
I think we could raise our ambition for how fast we improve our programmes by a lot. Today, our pace of change leaves a lot on the table. AI tools are allowing startup engineers to build 3x as fast; at digital-first development organisations, the pace has barely moved.
This is partly because fewer of our engineers visibly build with AI, though those who do have doubled their output.

Development organisations
Share of engineers with no sign of AI agents
But what seems like the biggest missed opportunity is that we're not trying hard enough to speed up: far fewer development organisations are asking their engineers to build with AI than in the private sector.
Few of us have been close to it
I think the reason is that very few people in development have direct experience of what's now possible. I looked at 40 effective development implementers, drawn at random from the grantees of five large funders.
of about 16,000 staff have ever held a technical job at a top 200 tech or AI company
has held one since ChatGPT
Unfortunately, the sector's tech advisers mostly don't have this experience either. To be clear, this is not a failing! The world is just changing really quickly (most of this happened in the last three years) and most of the sector simply hasn't been close to it.

If you haven't seen how fast things now move, it's hard to know what to ask for, even from the people you hire or contract to build technology.
An institution that doesn't understand digital is a very poor purchaser of digital products and services … We lack the internal core competence to outsource well.
How do we bring more frontier ambition to the sector?
I think that the way we capture this opportunity is mostly by expecting more. That looks like leaders asking if we can build in weeks rather than quarters, or test many versions of an idea rather than one. At the frontier, raising that expectation is now a big part of senior leadership's job.
The hardest part about doing this is simply just expanding your thinking … of what's possible in an unreasonably short timeframe. When folks say … ‘We can get this done by this timeline’ … part of your job now is to elevate everyone's ambitions and say, ‘Actually, isn't the possibility ceiling meaningfully higher? Shouldn't we be more ambitious …? Or couldn't we try this faster?’
This isn't to say that every organisation should hire a big team of expensive AI engineers. The labs are building the models and many of the products, as Chapter II argues. What matters is just increasing the density of people who know what the frontier makes possible and who can help leaders raise their ambition to match.
I can see three sketches of ways to do that. I'd love to chat about these ideas!
| What it is | What it gets | The risk | |
|---|---|---|---|
| New organisations | New implementers with frontier ambition and culture from day 1 | A clean sheet to think big from | A clean sheet on the really hard stuff: trust, relationships, distribution |
| Upgrade existing organisations | Increasing the ambition and speed of already effective orgs Starting Labs within big orgs to try new things at a new speed | Programmes, reach, and a team obsessed with the local context that makes the difference | Changing culture is really hard (especially without market feedback to force it) Labs risk becoming innovation theatre |
| Outside help | Scale existing support from teams like Agency Fund, IDinsight, Tech4Dev Embedded builders, like Anthropic’s Claude Corps | Scarce frontier talent shared across the sector | Orgs end up reliant on outside help, which is missing context from the ground |
