And I was curios how that profit is made, how many of their servers are being made and how widespread are they. I asked for some market share numbers so that we can get past those cryptic revenue figures that don't tell you anything. I am assuming you didn't found any and well neither did I, that has to mean something on it's own.
IBM is doing a lot of not so sexy things that really don't benefit a whole lot from big media coverage. As mentioned. The financial world depends for a great deal on IBM mainframes, I worked with them myself until just a few years ago and they are only now getting
very slowly phased out... and already companies are coming back to it or thinking about it, because the value of a mainframe is ironically enough increasing again as the trust in external suppliers for web clients and cloud isn't proving trustworthy enough (or these suppliers cannot really provide a higher burn rate for Change as mainframes could with in-house programmers). And its not impossible to build a web interface around a mainframe either, or at least connect to it. The biggest problem these mainframes have is age and a knowledge gap as the world moved to web based software.
The reason they are big into quantum computing is because that is the next big step for their core business. They need to be first, because if they are not, they cannot provide the security in their applications that they need to guarantee. Quantum is the key to unlock current day encryption for example.
Also about that revenue... the whole beauty of that number is that it captures a company's relevance perfectly.
TL DR IBM is on a whole other level as AMD, and certainly not a lower one.
