The skills gap is bigger than you think.
Many of the old pharts like me were involved in a bigger or smaller way with the JET project, we made the bits that assembled into the torus.. complete with high accuracy demanded by the scientists
Sadly a lot of the older pharts have now retired...... I'm 6 yrs away give or take a couple of months. and do we have the skills needed to make the parts for the project.?.. doubt it.... anyone sane with the skills needed ends up in Formula one manufacture or aerospace
Having the guys able to design the thing in one hurdle... having the people like me to build it is another
And those capable of either thing dont go into a messy dead end job that pays badly when they can sit in an office in a bank and make a shed load more cash.
