There are still Classic Visual BASIC programs out there that haven't been ported to VB.Net or C# yet because of how huge they are and how hard it is to code that they cannot afford to hire developers to do it for them. The same is true of many old languages like COBOL.
I heard that some places still using Turbo Pascal for DOS and have to stick with 32 bit machines because 64 bit can't run 16 bit DOS code.
Yes, and you similarly can continue using python 2.7.18 for next 10 years, no one expects Microsoft to continue releasing new versions of the classic VB. A lot of python users have weird expectations.
