It is easy to criticise legacy code, @bitboss.bsky.social offers a pragmatic reality check. Architecture modernisation requires empathy for the context in which the original system was built. Without understanding the "why" behind the legacy, resistance to change will remain high.

Is your legacy system modernization hitting a wall? Michael Plöd shares why respecting the "rockstar" developer's legacy is the key to turning resistance into architectural success.
