Not completely agree, I work at a company who makes money with semantic web consulting. It is really powerful technology, which we use to index and unify customer data, but also for dynamic React front-end generation.
I was a bit hesitant to start working at this company, because of the many negative notes here on HN (https://hn.algolia.com/?q=why+the+semantic+web)
This contrasts with what I experience, we have a growing customer base, both in healthcare and finance. Just do a LinkedIn job search with a keywords like 'sparql' or 'semantic', you'll see many jobs.
