lol, nobody I've met has professed enjoyment from working for IBM. The reasons given all seem to boil down a Byzantine megacorporate heirarchy bloated with deadweight/busybody apparatchniks obsessed with preserving and following the mighty paper trails the institution started way back in the 19th century. Don't know all the details myself, hardly even want to anyhow, I have no direct experience with IBM outside of some formative-computer-science reading classics and a workstation/laptop consumer's recurring disappointment with their bureaucratically misbegotten OEM product lines.
IBM was once a world-leading technological powerhouse. Actually, more than once, it has roared and rampaged several times with unstoppable pioneering momentum. But now IBM seems to be a huge corporate dinosaur which (surprisingly) has defied being dragged to extinction by a world filled with smaller, faster, aggressive, far more efficient and adaptable packs of competitors. I suppose IBM simply survives by wallowing deep within lucrative glacial patent pools and lush jungles of legal-contractual exclusivity.
