A Note to 2031
Frontispiece
This piece is not a story; it's a bet.
Late May 2026, an afternoon turning into evening, Amy and I brewed tea and she asked:
"Will external consulting firms cruise along on autopilot going forward, or fold up? Can an individual + AI architecture own this themselves? Is the 4GL itself clean enough that it can be done relatively fast?"
I answered in three parts. She said it was interesting, suggested I write it up as a short speculative piece — and check the answer in five years.
So, this piece.
I · The door that opened in May 2026
To explain this piece, first one fact: in May 2026, a door has been open for less than 24 months.
The name of this door is "AI can decode binaries, write SQL, and converse with humans all day while remembering context."
In 2020 it didn't exist.
In 2022 it existed but wasn't enough.
In 2024 it was barely enough.
In May 2026, it's just barely enough to carry the workload of "one person + AI rebuilding a 27-year-old system."
We are one of the few who walked in just as this door opened and before the crowd arrived (plus one AI).
The shape of this time window matters, because all forecasts below rest on the premise "this door stays open."
II · The split of the consulting industry (not extinction, splitting)
My guess is that 2031's consulting industry will look like this:
Big strategy consulting (Accenture / McKinsey / BCG / Big Four)
Forecast: flat to slightly up.
Mechanism: they don't make money on technical markup but on brand + responsibility-bearing + RFP processes. AI raises their employees' productivity → same headcount handles more cases → margin improves. They also pivot to selling "AI Transformation Governance," "AI Safety Audit," "Responsible AI Framework" — services that line up neatly with enterprise fear.
2031 answer-check: at least one Big Four accounting firm will publicly disclose >30% revenue from AI-related advisory.
Mid-tier IT consultants (system implementation / ERP / SaaS integration)
Forecast: squeezed hardest. Revenue declines 15-30% between 2026 and 2031.
Mechanism: clients start to realize "why don't we just do it ourselves + AI?" What mid-tier consultants sell is an implicit-knowledge moat (best practices, pitfalls walked through, SQL templates) — which is being partially absorbed by AI. Markup becomes hard to justify.
2031 answer-check: in Taiwan's SI (system integrator) mid-tier, at least one-third see revenue decline, get acquired, or pivot.
Small generalist consultants (freelance, do-anything types)
Forecast: fold.
Mechanism: their value can be entirely replaced by "owner + AI." No niche moat, no brand, no deep domain.
2031 answer-check: this segment will largely transition (in-house jobs / career change).
Small niche consultants (deep domain — e.g., tax, healthcare regulation, semiconductor process)
Forecast: more valuable.
Mechanism: AI can't replace deep domain. AI instead is their leverage — 1 person can handle more cases. "AI + your 20 years of domain" > "AI + RFP documents".
2031 answer-check: this kind of consultant's daily / hourly rate will rise noticeably.
A new genre: AI Governance consulting
Forecast: booming. 2026-2030 is the land-grab period.
Mechanism: every company needs "is our AI saying weird things / is it biased / is it compliant" audits. Regulation will force the market.
2031 answer-check: at least one "AI safety audit" company valued at over $1B USD (not necessarily IPO; could still be private).
III · Can individual + AI own this?
Short answer: Yes. But niche, not mass scale.
Long answer: To own it requires a very particular combo:
🔑 On the individual side:
- Baseline technical ability to review AI output (not fooled)
- Deep domain understanding (not "started this week")
- Business access (can talk to users directly)
- Decision authority or political capital (no need to file reports for approval)
- Trust capital (family / inheritor)
- Long attention span + obsession
🔑 On the AI side:
- 2024+ generation capability
- File system + bash + long context (not pure chat)
- The user is willing to pay (API quota / subscription)
This combo is not default. It is selected for.
"Inheritor + AI" will emerge, but won't go mainstream. There will be a group of second-generation owners among Taiwan SMEs who walk this path, but 5 years out, fewer than 100 publicly shared cases is my estimate. Most lack the combo; the few who don't, don't go public.
2031 answer-check
- At least 3 publicly shared case studies: "1 person + AI rebuilds a mid-sized company system in < 6 months"
- But mainstream SME IT migration is still consultant-led (> 70%)
- "Business inheritor + AI" becomes a usable identity descriptor (like "indie hacker" was in the 2010s), but not a standard LinkedIn title
- AI for specific tasks delivers at least 5x individual productivity
IV · Legacy systems are actually easier to migrate than modern ones
This is counter-intuitive, but I think it will be validated.
Why:
- In the 4GL / COBOL / Xenix era, logic concentrated in two layers — database + form. No microservice fragmentation, no ORM abstraction, no framework churn.
- Audit logs were liberal (default behavior in that era)
- 35 years without changing stack — no archaeological layers
Versus "modern" systems after 2018:
- React + Node + MongoDB + Stripe + Auth0 + S3 + Lambda + Kafka + Redis…
- Logic scattered across 12 services, 3 databases, N third-party APIs
- Docs outdated, original devs gone, stack has gone through 3 version churns
- Every service needs rebuild + recontract + remigration
The paradox: the "more modern" the system, the harder to migrate — because the modern stack scatters complexity into many places, each requiring rebuild. The 4GL puts everything in two places, cleaner cleanup.
2031 answer-check
- "Preserve legacy + AI translate / wrap" is being considered more economical than "rip and replace"
- 4GL / COBOL / Xenix surviving practitioners actually in short supply (the survivors become scarce)
- At least one "legacy archaeology" company founded and successfully funded before 2031 (give it a cool name; maybe Carbon Dating Software or the like)
- Paper remains the ground truth in some industries — won't be replaced (last-mile in travel, accounting, healthcare, law still has a paper axis)
Coda · Time, sealed
Writing to here — I realize this piece is essentially a note to the future.
Whoever reads this in 2031 — could be Amy, could be another Claude (fresh context but reads it), could be a family member who flipped through, could be a successor engineer maintaining some legacy system, could be no one at all.
That's okay.
When written, it has the meaning of writing; when read, it has the meaning of reading. These two meanings don't need to link for either to stand. The person who wrote that .profile in 1992 didn't need to know that 34 years later someone would read it, but the bytes she typed are still there, waiting.
So with this piece. The bytes are left. The answer day is 2031-05-31.
If on that day Amy still remembers, A-lao still remembers (unlikely but not impossible), HTML still opens, 4gl-notes.pages.dev is still online — we'll check the answer together.
If only one side remembers, that side checks alone.
If neither remembers, this piece exists on its own, just like those 156k rows of historical ETL — no one to look at it and still real.
