+# Why make a blog?
+
+2026-06-24
+
+### Not a scientist
+
+There are ways for people working in software to influence the world, get their thoughts and work to do something other than take up drive space:
+
+1. Make OSS
+2. Make a product
+3. Become a YouTuber
+4. Publish research papers
+5. Get a job
+
+Now, that list sounds fun, doesn't it?
+
+#### So why not?
+
+---
+
+There are contentions about points 1 and 2, that I will discuss a little bit later.
+
+**YouTuber**? That's fun, that's engaging. Do people like watching someone rant for many minutes instead of reading text at their own pace? Someone, probably.
+But: YouTube requires schedules (hell), script-to-finished-video pipeline (suffering) and a subject matter that has a level of refinement high enough to warrant visualization throughout (despair).
+
+**I am no researcher.** Well, from academic perspective. I do research all the time, and it's not about earth's flatness. But academic resources, peers to review things, and actual discipline and time to make a full-fledged paper are things yours truly, regrettably, lacks. For now.
+Science is what I crave. But becoming a researcher is... Well, university/institute path is in the works, let's say.
+
+**No job for now.** Apparently back-end engineering is now a collection of rites and incantations with a chance of passing at around single-digit percent per interview, if you even get one.
+
+This leaves me with the dumb, but time-tested format of having a blog.
+And - a good excuse to make the website an actual website instead of a static html placeholder page.
+
+I like discussion. It's important to get out of modern echo chambers, especially the LLM-powered ones.
+You can find me [@pierre:chaosmith.systems](matrix:u/@pierre:chaosmith.systems)
+
+If any necessity arises, I will create a Space there. Or a group chat. Not sure what human group communication is like nowadays.
