Seemingly, most companies have a terrible ability to judge if a technology is superior, hell most of the time they lack the ability to judge if a technology is massively inferior. Companies may understand what they do but they commonly have no understanding of what they do in relation to the abstraction layers between them and said technology.

Often this technology has been in place for some time and the original creators are long gone for one reason or another. To migrate away from this system the business will need to spend a significant amount on contractors/consultants to understand both the system they have well enough, and the system they are moving to. It can be a huge expense and companies are very willing to push that off into the future.
