It's the same with all trades, every trade has had to evolve, and I bet every trade has its moans about how things aren't the same anymore. How many heating systems are 90% plastic push fit, the stuff that is copper is crimp fittings. I imagine the older plumbers are moaning about the old days of mastering solder joints etc.
The likes of FP is an evolution just like any other, quicker to terminate, not really a dumbing down of our trade, micc still has its use, Petrochemicals, buildings of historic relevance, but where this isn't required, why use micc or any other cable for that matter when there is no need of it, just to try and hold onto times gone by. Would you use SWA where it wasn't required just because it takes more skill to terminate than T&E. Yes there has been a dumbing down of the domestic side of our trade, this allowed by a government that pays more attention to the dangers of gas and seems to think electrickery is a harmless thing. However in the commercial (where I do most of my work) and the industrial sectors, these Electrical Trainee's wouldn't last an hour, unless going in eyes open as a trainee/mate/improver.
A lot of the commercial stuff I do still involves the usage of proper containment, galvanised conduit, tray work forming our own bends, reducers, stuff that took time to learn and takes time and practice.
Granted some of the stuff done or seen nowadays will not be to the taste of some of the longer serving among us but it's evolution and things won't change apart from advancing further. I mean come on a lot of our stuff nowadays on commercial works is plug and play, click and connect, I don't like it but it's how times are changing. Our skills are most used in containment and fault finding over the installation itself but that's how it is now.
