Yes, if you treat it as an instrument, not an audience product.

The main value of a personal blog was never distribution. It’s externalized thinking. Writing forces you to make assumptions explicit, notice gaps, and resolve contradictions. That doesn’t get replaced by AI — if anything, AI makes undisciplined thinking easier to hide.

The posts that tend to compound aren’t “explainers.” They’re records of decisions, trade-offs, failures, and mental models you’ve actually tested. That’s where perspective comes from, and that’s the part AI can’t synthesize for you.

If starting today, I’d optimize for low friction and long half-life: short notes, irregular cadence, one theme you’re actively working on. Treat it as a public lab notebook. If it’s useful to your future self, it will eventually be useful to someone else.
