alt Hacker NewsAppreciate the love, but I think you are drawing the wrong conclusion here: Sun failed to endure not because it loved its customers, but to the contrary because it lost track of them: the company was disinterested in the mechanics of running a business.[0]
As for Oracle and its putative endurance, I would liken it to the Berlin Wall: despite the seeming permanence, it is in fact an artifact that history will be eager to forget when given the opportunity.
Per above, it seems like Sun had a core architectural, technical, and engineering failure with SPARC failing to keep pace with x86, and a business failure dealing with the fallout:

In contrast, HP mostly (though it eventually split into two companies) managed to survive Itanium and compete with Dell. IBM continued to evolve Power and its other architectures and still sells AIX as well as Linux systems. Cray still exists as part of HPE. Apple migrated from PowerPC to x86 before hitting a home run with their own version of ARM.
In an alternate timeline, I imagine Sun still existing as an independent company and being the leader in RISC-V systems. But I guess Oxide is something of a successor?
