The software is was written in the 60s and patched, patched, patched... I knew someone who worked on it, he passed away in the late 90s.

Plus tax laws change every year, in many cases causing massive changes. Every conversion failed because no one is left fully understands the whole system.

Plus for a conversion, you need a long quiet time, with the tax laws you never get that.

Not to mention, even with Biden's additional funding, which I am sure it will be cut, it is far from the amount needed for a successful project.

So here we are. I think some "modernization" has occurred, but the core system is still running some 60 year old software.

Note, I knew a lot of people who worked there prior to 2000, so maybe what I know is a bit out of date. But I doubt it since the attempts I have read about over the past 20 years did not succeed.
