How do I cope with my craft dying out?

You can hold tolerances by feel that machines still cannot match. That is decades of your hands learning what no manual can teach. And you are watching that craft fade faster than you can hand it to anyone willing to learn. That grief is real, and it deserves to be named, not brushed off. Some of this you cannot stop. Trades shift, and the world moves toward machines whether or not it should. Grieving that is honest. But grief and helplessness are not the same. The craft does not have to die completely with you if even one person carries a piece of it forward. So put your energy where it can still land. Find one apprentice, one young worker, one curious person, and pour what you know into them, even slowly, even imperfectly. Write it down. Record yourself working. A craft does not need a thousand heirs to survive; it needs one. Start looking for that one person now, while your hands can still show them. What you pass on outlives what fades.
