I believe parent is referring to design at the PCBA level, where this is mostly true outside of military/government designers who lag.
The reality in that sphere is there is little reason to limit oneself to the constraint of expertise in analog circuit designs when one can achieve the same functional outcome digitally, and use those skills more broadly.
Only where component sourcing is artificially limited, or risks of digital operation sufficiently large, and where the job market will support it, does it make sense to proceed in growing in analog circuit design expertise.
Meanwhile these designs are nearly all being functionally lapped by those in general industry, which participates in all the accelerating gains of digital technologies.
