What I hate about IT is you went to college, got a master maybe, go certified in Sysco or Linux or FORTRAN or cobalt or Novell. Next thing you know something new comes out and you got to learn it.
How many different new things have you learn throughout your career? I could never do what you do.
Cisco.
But the technical certificates don't teach the skills of how computers interact with systems. COBOL is a long dead language. Even when I went to Cal Poly for my bachelors the world had move on to C and other such languages. The point though is that a CNA will certify a technician, not a systems administrator or manager.
You can't design a system to manage inventory if you don't grasp the concepts of product flow, increments and decrements of locations, dimensional inventory where product changes nature. Masking a subnet does nothing to prepare one for this. And yes, I can mask (IP v.4) subnets by hand using binary masking if needed.
Big picture does require higher education. I make no secret that manufacturing, production is my focus. I use technology to empower production. Multitier product flow across diverse locations with gazintas altering the form fit and function of elements requires meticulous design. It is not the job of technicians.
I obtained an Sc.D. because I needed the skills to pursue my goals.
