I client of mine still has a fairly large piece Delphi of code in production and I must say it&#x27;s a bit of a liability for them. An example of a technical problem they face is getting the particular version of Delphi they use work with TLS (and that&#x27;s becoming a problem now as everyone&#x27;s starting to disable SSLv2 &amp; SSLv3). The fact is that they simply wouldn&#x27;t face this kind of problems if they have ported their code to something like Python, C# or Java.<p>On the non-technical side of things, they also struggle with hiring developers who are capable of (or willing to) work with Delphi, especially junior developers. A significant portion of their staff also doesn&#x27;t know how to work with Delphi, so reassigning resources to match the needs of the business is often a challenge.<p>I imagine these issues would probably apply to Fortran as well.
