Cau chuyen khong dung lai o Boris. Mot nguoi khong hoc khoa hoc may tinh, khong qua mot lop code nao, da tu lam va launch mot ung dung smartphone ten “10 phut guitar” ma khong tu viet mot dong code nao. Toi da thu kiem chung theo cach don gian nhat: dung Claude tao mot web app CRUD hoan chinh tu dau. Thoi gian thuc su danh cho code thuong duoi 20% tong cong suc — phan con lai la mo ta yeu cau va review.

Cach nguoi dung su dung bat ngo chinh la kim chi nam san pham

Usage-based discovery la phuong phap tim huong phat trien san pham thong qua cach nguoi dung thuc su su dung, khong chi thong qua y dinh ban dau cua team.

Hai vi du kinh dien:

Facebook Group → Marketplace: Ban dau chi la tinh nang group. Team nhan thay 40% bai viet la mua ban. Ket qua: sinh ra Marketplace — tinh nang do chinh nguoi dung ep buoc ra doi.

Cowork: Ra mat nhu cong cu AI cho developer. Nguoi dung hoi ve cach trong ca chua, cach phuc hoi anh cuoi, vo so chu de linh tinh. Tin hieu ro: nguoi dung muon mot AI da nang, khong chi tool cho dev.

“Dung hoi thang cat rang rang ‘Ong co can cat toc khong?’. Hay nhin xem khi ban khong co o do, ong lam gi voi cai keo.”

Doi voi san pham Viet Nam, dieu quan trong khong phai la “giai thich cho nguoi dung cach dung dung” ma la ghi nhan lien tuc nhung cach dung sai y, phan tich xem pattern nao lap lai, va xem do co phai la huong phat trien moi hay khong.

Toi da thay dieu nay xay ra that. Mot tinh nang chat AI nho ban dau chi nham ho tro tra loi FAQ, nhung noi bo “dung chuyen” no de tong hop bao cao — cuoi cung, do moi la gia tri chinh cua no. Neu team ep nguoi dung “dung dung cach”, co le da cat mat tinh nang hay nhat minh tung co.

“Software engineer” se bien thanh “Builder” da linh vuc

Builder la nguoi co the bien y tuong thanh san pham hoan chinh, duoc ho tro boi AI, bat ke xuat than ky thuat hay phi ky thuat.

Du doan cua Boris: tieu de “software engineer” se dan dan mo nhat di. Thay vao do, ai cung co the “build” — PM tu tay lam POC, designer tu tay lam prototype co backend gia, data analyst tu tay lam cong cu noi bo nho, ke ca ke toan hay nhan su cung co the lam tool cho chinh minh.

Trong moi truong nhu the, ranh gioi giua cac chuc danh bi xoa nhoa dang ke. Mo hinh “T-shape” (mot chuyen mon sau, vai thu khac biet) dang dan chuyen thanh “comb-shaped” — nhieu cot chuyen mon, vua sau vua rong.

Nguoi chi biet sau ve mot ngon ngu, mot framework, mot loai he thong se rat de bi AI thay the dung diem do. Nguoi hieu duoc nhieu linh vuc va noi ket duoc design–code–du lieu–business se tro thanh bo chuyen doi giua cac the gioi ma AI van con kho “cam nhan tong the”.

Toi da thay dieu nay o Viet Nam: nhung ban dev biet lam ca UI, biet doc so lieu marketing, biet viet noi dung co ban cho landing page, dang di rat nhanh truoc phan con lai cua thi truong. Khong phai vi ho gioi hon — ma vi ho khong cho phep minh chi gioi mot thu.

Quan sat noi tai: Theo doi cac don vi giong “neuron” ben trong model, nhan dien luc nao no “sap noi doi” hoac co dau hieu lech chuan.

Mo phong va kiem thu: Dat AI vao nhieu tinh huong gia lap, kiem tra no hieu va phan ung voi cac khai niem nhay cam ra sao.

Theo doi hanh vi thuc te: Nhu truong hop Claude Code — dung 4–5 thang trong noi bo truoc khi cong khai, ghi nhan bug, rui ro va han che trong thuc te su dung.

“Day khong con la muc ‘hy vong mo hinh se on’, ma la ‘lam cong cu thuc su de mo bung no ra ma xem’.”

Chung ta la phileng sa, va AI la may in Gutenberg

Analog Gutenberg la cach so sanh buoc nhay ve AI voi cuoc cach mang may in cua Gutenberg trong lich su nhan loai.

Truoc may in, duoi 1% dan so chau Au biet chu. Moi hoat dong doc–viet deu phu thuoc vao phileng sa — nhung nguoi chuyen sao chep. Sau may in, chi trong 50 nam, so luong tai lieu in ra da vuot ca toan bo lich su truoc do cong lai.

Phan ung cua nhieu phileng sa khi do:

“Tot qua. Khong con phai ngoi copy tung dong kinh sach nua. Gio moi co thoi gian lam nghe thuat thuc su.”

Thong diep cua Boris: chung ta chinh la nhung phileng sa thoi nay. AI chinh la may in cua the ky 21.

Cau hoi khong con la “AI co cuop viec khong?” ma la: khi duoc giai phong khoi viec lap lai, chung ta se lam gi voi thoi gian do?

Toi da tu hoi cau nay trong chinh cong viec hang ngay: neu AI viet code, viet test, viet tai lieu 70–80%, phan 20–30% con lai minh danh de lam gi — thiet ke san pham tot hon, noi chuyen voi nguoi dung nhieu hon, hay chi di hop nhieu hon?

Ket luan: 7 chuyen bien can chu dong om lay

Tu 12 insight cua Boris, co the rut ra 7 chuyen bien lon:

1. Coding la bai toan co ban — bat ky ai cung co the build neu biet dien dat y tuong tot.
2. AI dang tham nhap vao “what to build”, khong chi “how to build”.
3. Nang suat 200% chi xay ra khi team chu dong cat nguon luc va ep AI lam viec that su.
4. AI can muc tieu va ngu canh, khong phai huong dan step-by-step ti mi.
5. Nguoi bat dau som va tin vao AI 6 thang sau se co loi the lon khi model moi ra mat.
6. Usage bat ngo la kim chi nam san pham — luon nhin xem nguoi dung dang lam gi “trai kieu”.
7. Chung ta la phileng sa — gia tri nam o cach dung thoi gian duoc giai phong, khong phai bao ve cong viec copy.

Voi thi truong lao dong Viet Nam, dieu nay dong nghia: lap trinh vien chi hoc syntax se rat mong manh, PM chi biet viet spec se rat de bi thay the, designer chi biet ve layout nhung khong hieu hanh vi nguoi dung cung gap kho khan. Nguoc lai, nhung nguoi chu dong dung AI nhu dong nghiep than can, chiu chi tieu tien va thoi gian de thu nghiem, va nam lay nhung cach dung bat ngo cua nguoi dung, se la nhung “builder” thuc su cua 5–10 nam toi.

“Gian viec copy da ket thuc. Nghe thuat chi moi bat dau.“

Cau hoi con lai chi la: ban muon danh phan “nghe thuat” do cho dieu gi?

Cau Hoi Thuong Gap

Q: AI da lam duoc den muc nao trong viec viet code — co the thay lap trinh vien chua?

A: Theo truong hop cua Boris va nhieu workflow tuong tu, AI da co the viet phan lon code can thiet de xay dung ung dung thuc te, ke ca cho nguoi khong biet code. Tuy nhien, con nguoi van rat can thiet trong viec dinh nghia van de, thiet ke he thong, ra quyet dinh san pham va kiem dinh ket qua AI tao ra. Vai tro cua lap trinh vien dich chuyen tu “nguoi go code” sang “nguoi thiet ke giai phap va cong tac voi AI”.

Q: Neu moi la junior developer, nen tap trung hoc gi thay vi chi hoc ngon ngu va framework?

A: Junior nen tap trung vao ba nhom nang luc: dinh nghia van de (hieu ro nguoi dung va yeu cau), thiet ke he thong co ban (kien truc, data flow), va ky nang giao tiep — hop tac (giai thich, tranh luan giai phap). Nguyen tac can ghi nho: han che dat minh vao vi tri chi lam nhung gi AI lam rat nhanh, va tang thoi gian vao nhung gi can goc nhin, phan tich va giao tiep cua con nguoi.

Q: Co nen chi nhieu tien cho cong cu AI khong? So dung khong het thi phi?

A: Chi phi AI nen duoc xem la dau tu, khong phai chi phi thuan tuy. So voi mot thang luong ky su, mot goi AI vai chuc trieu mot thang van re hon rat nhieu neu no giup tang nang suat hoac mo ra co hoi san pham moi. Rui ro thuc su khong phai la “lang phi token” — ma la “khong cho y tuong co co hoi duoc thu nghiem” chi vi ngan sach AI nho.

Q: Neu AI ngay cang thong minh, con gi la loi the cua con nguoi?

A: Loi the nam o kha nang noi ket nhieu linh vuc, hieu ngu canh xa hoi–kinh doanh, va dua ra quyet dinh co y thuc ve gia tri va dao duc. “Builder” gioi nhat se khong chi sau mot chuyen mon, ma con biet ket hop thiet ke, ky thuat, du lieu va business — nhung nut noi ma AI hien chua lam tot, dac biet trong moi truong nhieu van hoa va rang buoc nhu Viet Nam.

Q: Cach nao de bat dau dua AI vao workflow neu chua co kinh nghiem?

A: Ba buoc don gian de thu: (1) Chon mot cong doan lap lai nhat — viet tai lieu, viet test, tong hop feedback — va giao cho AI ho tro. (2) Chap nhan chi phi tuong doi cao trong giai doan thu nghiem de tim cach dung phu hop. (3) Ghi lai nhung cach dung bat ngo hieu qua va chuyen no thanh quy trinh chinh thuc. Khi do, AI dan tro thanh dong nghiep co dinh, khong chi la cong cu thu nghiem.
