Basically this. The people running the show would desperately like to make it simpler, but ultimately it’s left overly complicated due to priorities from past leadership well above our paygrade.
The right solution is always to just rip off the bandaid and do it again by hand in a new language or platform, and to eliminate useless complexity while doing so. Unfortunately no leader would ever do this because the Board and/or Shareholders would crucify them for not outsourcing it to McKinsey first and using the fancy-pants automation tool their report recommended.
