I have no issues with VB itself, but the technology is long obsolete and any organization that still has it somewhere in their business is taking on risk that should have been mitigated years ago. Realistically, these apps are not simple apps with a few buttons. I happen to know that the complex, business-critical VB6 app used by the company I interned for 25 years ago is still out there, still supported by the original team! That's a ticking time bomb, as far as I'm concerned.

BTW, the VB6 experience is still somewhat attainable with .NET WinForms (can even use VB.NET if you so desire). Showed my kids how to build simple apps a couple years back and the overall process of dropping controls on a canvas and wiring up events was pretty much the same.
