My company recently acquired another and picked up some interesting legacy infrastructure: on-premises mainframes running COBOL. What I found particularly funny is that this system has deprecated but still in-use legacy components of its own, like a telnet server, and that this legacy component also has legacy components that may or may not still be in use (character mappings for specific teletypes that different remote clients used).

I guess that at some point, everything any of us do will become someone else’s headache.

for the lazy, since i already made the effort:

On a long enough time line, all technology runs on archiac magic.
