I’ve been lurking for two months.
I’m an IBM mainframer since 1970. Coding pads, punch cards, tape drives & all that.
Fascinating maintenance challenge to keep the legacy systems — where definition of “legacy” is something that works, regardless of 40+ years old or a day old — is a huge opportunity for people with project management skills.
Since software is an invisible, largely unmeasured resource—I do NOT like to use the word “asset”… that’s the domain of the CFO & balance sheet—effectively maintaining software is a challenge.
Little factoids on scale…
1/ - IBM takes home $25 billion in annual net PROFITS from mainframe hardware, software & service. Mainframe applications are not going away.
2/ - there are some 50 major software languages, 1,500 minor languages & a new language is introduced at the rate of one a month.
3/ - 350+ DBMS Engines

4/ - Apple’s biggest customer is IBM. https://www.apple.com/business/success-stories/ <https://www.apple.com/business/success-stories/>
