The AI and quantum roadmaps are an albatross for a company like this. They'll always come up in 2nd place or worse. The competition is insane. Meanwhile, there are maybe 3 other humans on earth with the means and conviction to build a competitor to their mainframe business today. It's one of the better moats in technology. It's not the biggest or most lucrative one, but no one wants to touch it because the captive audience would never risk an alternative.
Data is still IBM's best hope. It's always what they've done well. Especially the very important "core" data of complex enterprises. Things like the account balances and transactions for all customers at a bank. DB2 is easily the most compelling mainframe service and I don't ever see that changing.
