the Microsofties viewing their IBM colleagues as mired in pointless bureaucracy and the IBM folks viewing Microsofties as undisciplined hackers.

I work at MSFT, this made me chuckle hard. Microsoft must have been a very different company back then, because now I find myself and my colleagues mired in pointless bureaucracy via endless meetings, AI mandates, promotion theatre and the list goes on. I am decently paid but the bureaucracy is soul destroying.
