Apples and oranges. Gutting fish has not changed a bit over the years. Same for lots of manual labor. Working on cars has changed drastically and now involves more computer savvy than pure wrench-turning.
No, it's not, but if you want a closer analogy...when's the last time you saw a paperboy?
It is intellectually dishonest to note gutting fish hasn't changed while ignoring everything else in the market that HAS changed.
When I first started working, managers would have sworn the safety standards we live by today would have drove them out of business. Now, they risk losing their business to lawsuits if they DON"T abide by those standards. So nothing changed, you say?
