They no longer need to. They have a core business to finance whatever stupid ideas ad infinitum. When was Oracle or IBM successful at anything new last time? Yet they chum along with 140k and 280k (!!!) employees.
280K is down from 400k+ when I worked at the latter 2 decades ago
Doesn't IBM still do high tech research? The only thing I know Oracle does is buy up companies to take over their products (and customers).
