Meanwhile, some small startup is using newer technology that makes them many times more efficient. And allows them to utilize their IT as a core part of their product, instead of an internal utility service. And stealing all your customers.

Of course, there are industries that are immune to startup competition due to the high barrier of entry (banks, insurance, governments). I don't think it is a coincidence that these are about the only environments where mainframes are still dominant.
