Or work with a random programmer at a random company for a bit. We had to do some audit/estimate for a company with huge tech issues (race conditions causing data corruption, huge slowdowns with just small usage spikes etc) costing them clients/money. The company runs around $50m/year or so selling software to enterprises. Anyway; software backend written with Java/Spring, deployed/updated on EC2 manually, no automated tests (zilch). Frontends with Vaadin. Almost no processes are used, just Jira + tasks and then 'start at the top every morning'. No one knows sql anymore (Hibernate), no one knows html/js (Vaadin) and, even though most people are senior and there since the beginning, no-one has done anything high level on the job in the past 20 years or so. They have just been inside this 'ecosystem' writing code and it works. Old Java with some modern updates just to satisfy the compiler/linter (but not fully understanding why that nonsense is needed). None of the core seniors I interviewed touches computers outside of work, they had 0 tech courses since working there etc. They are all 9-5 code producing robots. I want to bet they can mostly/all be replaced today by Claude Code, of which existence, of course, they are not aware (they did chatgpt but not Codex or Copilot). We have since found so many issues in the code. Yeah, I do feel very much uplifted about my own skills after encounters like this, and these are by no means rare, i would rather say; extremely common.

Unlike OP though, I cannot be as open about these companies as we would definitely not have any clients left after.
