Exactly. When I joined the company I'm at now (consumer energy industry), the energy crisis hit and the servers melted from all the people looking to fix their contracts etc. I wasn't directly involved, but loads of developers did a mammoth effort to rewrite old services to prevent this from ever happening again.

New energy crisis this year, the servers held, the company made a lot of money from new contracts via a combination of getting lucky with long-term buy-in contracts and the servers staying up unlike the competition. But there were no heroes, no praise to e.g. the developers putting in the extra hours, etc - it was business as usual, or business as it's supposed to be.

I've been noticing this as a solo dev. I need to put lots of work into infra and security, and all I get for it is... the thing not blowing up (hopefully!).

The work is invisible, and impossible to "show off", so it's a bit unrewarding and demoralizing. But hey, someone needs to do it!
