Fame
As it turns out, machinists' names are littered throughout history. You just never knew they were machinists. Think back to your American History class—do you remember Eli Whitney, inventor of the cotton gin?
We can even expand into World History: does the name Josip Tito sound familiar? While Tito's known as the former authoritarian leader of Yugoslavia, he also trained as a machinist's apprentice (source). Sure, it may not be the fame you were thinking of...but it's fame nonetheless.
Unfortunately, you probably won't reach any kind of celebrity fame as a machinist. It's just truly not a very glamorous career. Few people know that there are people fabricating the things they use on a day-to-day basis, much less what exactly a machinist even is. Sorry to say it, but if you have dreams of chatting with talk show hosts about the hilarious hijinks you and your fellow machinists get into, you've got some weird dreams.
And that's coming from people who regularly dream of sharing earl grey tea with Picard while riding a liopleurodon through Atlantis.
