The Clock You Can’t See From Across the Table
Zack Shapiro’s “The Two Clocks” is right about the biggest problem in AI and law. Here is what it looks like from inside a firm.
Zack Shapiro’s The Two Clocks is the most accurate account of the AI-and-law problem I’ve read from anyone standing outside a firm. His argument, in one line: AI capability has raced years ahead of the institutions meant to use it, and the gap between the fast clock of the technology and the slow clock of the firm is the real story. Most of what follows is agreement. The rest is what that picture looks like from inside one, where I run AI and innovation for a national practice and spend my days in the exact gap he names.
Start with where he’s right, because he’s right about the thing that matters most.
The bottleneck really has moved
The line I’d underline twice is his: the bottleneck is no longer the intelligence, it’s the absorption of it. That is the whole job. The capability has been good enough for real work for a while now. The deployed value hasn’t followed, and the reason isn’t the model. It’s everything around the model — the process, the supervision, the standards, the person willing to change how the work gets done.
I’ve made this argument in narrower terms. The last mile in legal has its own geography, a specific terrain of hazards that general adoption advice never names. And the productivity numbers everyone quotes come with an entry fee nobody reads aloud: the data, process, and supervision preconditions that have to exist before a 3-to-5x number means anything. Shapiro’s version — a very expensive motor bolted into the old driveshaft — is the same warning in a better metaphor. Procurement is not absorption. On that, no daylight between us.
His workshop anatomy is correct too: task, background, judgment, constraints, deliverable, verification. And the most important sentence in the essay is the one pointing out that none of it is technical. The lawyers who take to this fastest are the best delegators, not the most technical people in the building. That matches everything I watch happen.
So here are three places the view changes when you move from across the table to inside the room.
Verification is not word six. It’s the new bottleneck.
In his anatomy, verification is the last item. In practice, it’s the whole game.
When production gets cheap, the constraint doesn’t disappear. It moves. It moves to the one step that didn’t get faster: a human deciding whether the output is right enough to put a name on. And that step does not scale the way drafting does. A model can generate a hundred competent drafts in the time it used to take to write one. It cannot make a partner able to actually read a hundred.
The demo where the mood in the room changes is real. I’ve run that demo. But it’s the easy half. The hard half arrives at the second thousand documents, when the drafts are landing faster than anyone can check them and someone approves one they did not fully read — not from laziness, from arithmetic. That is a selection problem, not a review problem, and you cannot review your way out of it. Every guardrail and eval only works after a human has decided what deserves attention.
Shapiro actually hands us the reason himself. Law has no compiler. A wrong contract doesn’t crash; it sits in a drawer until it detonates. That’s precisely why verification can’t be the sixth thing on the checklist. It’s the thing the whole rebuild has to be designed around. He says the words and then walks past them.
The surplus doesn’t have your name on it
The essay’s engine is optimism about who keeps the money. The frontier labs are General Electric; the firm that rebuilds itself is Coca-Cola. Absorb the capability and the margin is yours.
From inside, that’s the claim I’d hold most loosely.
Efficiency that everyone can buy flows to the buyer, not the producer. When every serious firm has absorbed AI — which is the entire premise of a race — the production savings get competed straight through to clients. You capture surplus from what stays scarce and hard to substitute, not from speed your competitor also has. His own evidence points this way: Blackstone is already paying Kirkland less, before Kirkland has rebuilt a thing. That’s not the fruit of absorption. That’s the surplus leaving through the door marked bargaining power.
We have the wider numbers on this. Eighty-eight percent of organizations use AI in some function; a single-digit share get measurable financial impact from it, and the playbook executives are running contradicts their own data. A rising tide has never lifted all boats. It lifts the ones rigged to catch it.
None of which means don’t absorb. It means be clear about which bet you’re placing. Absorbing to keep up is survival — the table stakes, the price of still being in the game in three years. Absorbing to win is a different move, and it doesn’t run on speed. It runs on the parts that don’t commoditize: genuine judgment, and the ability to stand behind the work.
The grind was doing something
Shapiro concedes, in roughly a paragraph, that AI compresses the junior grind that used to train lawyers, and that firms will have to “design training around decision-making deliberately.” That paragraph is carrying a fifteen-year problem it can’t lift.
The grind wasn’t only what firms sold. It was the transmission system for judgment. First-pass research, first-pass drafting, the diligence nobody enjoyed — that was where instinct got built, through repetition and exposure and being wrong in front of someone senior. Take the reps away and you keep this cohort’s judgment while quietly starving the next one’s.
There’s early evidence the trade isn’t free. In one study, developers who learned a new library with an AI assistant scored worse on understanding it afterward than those who struggled through without one. Speed for skill, and sometimes you get neither. Meanwhile the judgment that survives isn’t the relaxing part of the job. It gets compressed into every minute of the day, because the easy work that used to space it out is gone. The premium is real. It’s also heavier to carry than the essay lets on, and the pipeline that produces the people able to carry it is the thing most at risk.
Some of the slow clock is the law of lawyering
One more, and it’s the one I can only say from inside.
Not all of the slow clock is cowardice and comp cycles. Some of it is the job. Privilege, confidentiality, malpractice exposure, the bar rules, the client’s outside-counsel guidelines — these gate what absorption is permitted, not just what’s possible. The Sullivan & Cromwell hallucination Shapiro cites as fear is also a genuine governance failure, and the lesson a careful firm draws from it isn’t “be braver.” It’s “build the process that makes that impossible.”
The rational firm isn’t only protecting its margin. Part of what looks like foot-dragging is protecting the client, and that part is correct. The work is to separate the caution that’s real from the caution that’s theater — and Shapiro collapses them into one. Governance isn’t the committee that slows you down. Done right, it’s the thing that lets you go fast without the filing that ends a career. It isn’t a step you finish. It’s a property of the system, maintained continuously or not at all.
What I’d keep, and what I’d add
Keep the clocks — the frame is the most useful thing published on this in months. Keep own-the-method over rent-the-wrapper. Keep absorption as the real constraint. On the shape of the problem, Shapiro is more right than anyone writing about this from the outside.
What I’d add is the part that turns his diagnosis into a defensible position. The durable moat isn’t the speed of your clock. It’s whether you can prove, on the record, that the fast work is also right — a verified, governed process a human genuinely stands behind. That’s the input that stays scarce when production goes to zero, because it’s the one thing the client can’t get from a cheaper tool or build themselves without taking on the risk they’re paying you to hold.
Absorb to survive. Differentiate on judgment and accountability to actually keep the surplus. Because absorption without verification isn’t the Coca-Cola fortune. It’s just a faster demo.
I write every week about the operational reality between an AI demo and deployed value — mostly from inside a law firm, where the stakes make the gap impossible to ignore. If that’s useful, subscribe.
