I wouldn't be surprised if the engineering staff at that Chinese company doesn't have a real engineering degree but some sort of "work experience" degree after serving in one of those remote technical help call centers.
That was the most ignorant thing I've heard in a while, "they're in a foreign country so they must be dumb and don't know anything". Many of the
sales staff have post graduate electronic design degrees.
It is very easy for me to pontificate here because I have all the experience required:
1) I helped many very non-technical artists help set up and maintain their "render farm" which is the finishing stage of ray tracing in computer animation.
2) I worked for many years in hardware design and I know how to recognize common hardware faults and properly fix them.
tldr something something computers in the 1990's so clearly know more than ASIC, electrical and software engineers combined. Could throw together an S7/SP50 killer in a weekend /s.
