His business seems to run on AWS Lambda, which is about as far away from running on cheap (unreliable) hardware as possible? The laptop he mentions is just for working.
The downtime he speaks of is developer downtime. He isn't implying he served from used Thinkpads before, or that he serves off of MacBooks now.
I don't think it's a huge deal, just keep your secrets backed up in multiple ways you can retrieve
Yeah, but ... what is in my hands can be replaced in a matter of hours: just go out and get a new laptop at the nearest place!
It's even easier than that, because I primarily use Linux, there are times, in 2023, that I used a Core2 Duo with 2GB of RAM for days at a time on a particular project.
That's about 10m to pull the old laptop out of the cupboard, due `git pull`, and carry on working.
