> Easy to say when you have one having been in industry for 20+ years

More like 10+. That is the network sweet spot. At 20+ your network is starting to gray out and mostly useless unless you have someone who has risen up to VP ranks who can influence some downstream director to move your resume to the top. At 30+ you are some younger person’s “network”. At 40 years (where I currently am) your “network” is frankly retired, dead, or just trying to squeeze out those last few years in a no stress role to keep their medical insurance and can be no help to you.
