Oracle is unlike any other technology company in the world. The majority of their software offerings are not aimed at consumers, so many people (including programmers and IT-savvy folks) have a hard time understanding the company unless they’ve spent weeks studying one piece of their product stack.
I started working for Oracle in 1998. I thought I would be able to get up to speed quickly on everything Oracle. I was wrong. It took a long time to get a feeling of confidence. The main product, the Oracle database, is a vast monolith of technology and features that is constantly being updated. It has a documentation set that could easily fill a bookshelf.

Every so often someone takes at shot at Larry at a press conference or online, implying that Oracle’s time has passed, that some new hotshot company was going to overtake them in some way.
Spend some time studying Oracle and Larry Ellison, and you’ll understand why Larry always smiles at these questions.
