There are more silos in the software engineering industry than you might expect as a "Big Tech" kind of engineer (assuming that's where you're speaking from). Gaming, embedded, audio, aviation, defense, automotive, medtech and pharmacy, deep enterprise, finance, etc.

Those silos maintain different processes and workflows, different company cultures, different skill specializations, etc and jumping around between them in mid-career or senior can be very challenging. So they tend to have their own org chart shapes and salary/benefit norms.

When a Big Tech company moves into or absorbs one of those silos, or emerges from one of those silos, it can shake up what the people within them get paid (and thereby have big knock-on effects for legacy employers), but otherwise it's just it's own little bubble in a lot of ways. People can share stories and ideas across the siloes in venues like HN, but many of the "what are you even talking about" reactions that happen on here often occur when people from these different silos stumble into what are sometimes deep differences in what they do and what their work experience is like.
