What happened
A self-taught electronics tinkerer demonstrated a working room-sized 8-bit computer built from 460 recycled 1950s Soviet 6N3P vacuum tubes. The machine takes 15 minutes to warm up and emits a burning-dust smell during operation.
Why it matters
This is a hobbyist curiosity with no practical takeaway for builders, developers, or founders — there is nothing here to adopt, decide, or change. Worth mentioning only as a fun conversation starter about how far compute infrastructure has come and what 'warm-up time' literally meant for early hardware.
Discussion angle
Use as a 2-minute icebreaker: contrast the 15-minute warm-up and 460-tube footprint of an 8-bit machine against the millisecond cold-start containers and serverless functions we ship today — a reminder of how abstraction layers have collapsed hardware complexity for modern builders.
