The need for quality professionals is likely to be less as Industry 4.0 comes more fully to fruition.  The digitalization of everything should significantly reduce the opportunities for errors.

One thing that will increase is the need for information security … at the device level, IOT communications, etc.  I would propose then that quality professionals might want to pursue knowledge in the realm of information security, such as management systems based on ISO 27001, NIST cybersecurity frameworks, and operational security standards such as developed by IEC.  And all this will require a significant understanding of risk assessment and management.
