I'm honestly curious what will happen to these systems in 20 more years when most of the skilled knowledge retires and the resources, documentation, and toolchain maintenance goes with it. Industrial automation from years past moved to hardware emulation to keep the binaries running on ancient oil refineries that would be wholesale replaced at some point.
The systems described in the article store real data that would need to be migrated, which may be locked in uninterpretable binary formats read using binaries which can't be run on modern hardware.
