Others will advertise for you... or simply pay attention when you do well. Being reliable is outstanding, a true rarity.
Plenty of folks will want to take advantage. Assuming you weren't actually hired to work alone in a closet, there will be opportunities to shine/get put on speed dial... if you really want that.
Plenty of people are in situations where they don't appreciate someone's value until they're removed, or want to exploit the person and conceal that the person, and not themself, is providing the value.
The flip side is, as the management abstractions go up, they have less visibility into who's providing the value, so people who sell themselves better will be perceived better than people who just assume their work will speak for them. If your manager is also an engineer, it's obvious how you provide value to them, probably, but what about their manager, or theirs?
This advice, like all before and after, is not some atomic function to keep mindlessly smashing.
It works well enough; I was born dirt poor and now struggle to have free time to enjoy my pile of gold. Despite doing zero self-promotion through my career, I'm exceedingly well-known. The work and others spoke for me. Too much, I'd say.
Have an environment where you need to regularly over-extend yourself? Find a new one, you're clearly desirable. Layoffs/life happens, whatever.
There are plenty of downsides from subscribing to the rat race, some upside too. Debasing nonetheless. Guess who has to control that ratio. You. Others will take everything being offered... and then some more.
If anything, I'm championing discretion. Filtering is important! Truly no judgement to those who choose to be more involved, just speaking on my experience. YMMV of course.
Stolen quotes to close: "it sucks to suck" or "that's life". Promotion is like terrorism, only have to be lucky once.
Thank you for coming to my crash TEDhn talk on Game Theory :)
