There's a piece of software that I use at work for managing tickets for a client, every time I open it there's a note that the app will be replaced next month on the 1st. This notice gets updated on the 27th of each month without fail by the end of day. For now critical infrastructure remains running on a windows xp machine that we remote into using the only software that let's people connect to it.

I have an idea how much energy is spent trying to replace older working systems with crap that doesn't. We definitely are failing.
