প্র ০৩ Foundation model era-এ "small CV engineer" relevance কোথায়? GPT-4V/Gemini আমার job খেয়ে নেবে?
Existential question — every engineer 2024+ ভাবছে।
What foundation model can do:
- Generic image classification।
- Open-vocabulary detection।
- Caption, description।
- Casual visual reasoning।
What foundation model cannot:
- Real-time low-latency (mobile, edge)।
- Domain-specific specialty (medical, satellite)।
- Cost-effective at scale।
- Integrate with custom system।
- Privacy-sensitive data on-device।
- Bangla cultural context (limited)।
Engineer role evolution:
- From: "train custom model from scratch"।
- To: "select foundation, fine-tune, integrate, deploy, monitor"।
- Higher abstraction, more business value।
New required skills:
- Prompt engineering — visual + text।
- Foundation model fine-tune (LoRA, adapter)।
- Evaluation — automated + human।
- Cost optimization — API vs self-host।
- Hybrid pipeline — small specific + large generic।
- Safety, alignment।
Bangladesh-specific opportunity:
- Bangla foundation model — currently weak।
- Local culture digitize।
- Cost-effective deployment for emerging market।
- Annotation industry scaling।
Career future-proofing:
- Stay current — read paper continuously।
- Build production system — not just train।
- Domain expertise — fashion, medical, agri।
- Soft skills — communication, business।
- Code rapid prototyping।
Reassuring:
- Internet didn't kill engineer।
- Cloud didn't kill SysAdmin (just changed)।
- Foundation model — engineer leverage tool।
- More engineers needed, not fewer।
মূল উপলব্ধি: "Replaced" wrong frame। "Augmented" right frame। CV engineer 2030 — different role, more strategic, equally valuable।
