No it isn’t. I tech infrastructure gets the same treatment as regular infrastructure: we don’t want to build a new one because the old one kinda still works and a new one would cost us money.

The reality is that you need to keep upgrading and building new infrastructure. Because inevitably the old one won’t work or no longer be enough to support the needs of the users. And when that happens, it will be even more painful and expensive to get it up and running again. And the best case scenario would be that no one loses their lives over it.
