It's all theatre for the folks that don't do it every day. Six years ago I watched as two bus loads of paratroopers went through the screening program and put their rifles through the xray machines at a UK regional airport before mounting C130s to do some parachuting. Someone was satisfied but it was a pile of poo.

Unfortunately they tried both at once with the 72" tall VAX9000 (standard VAXen were 60") and the various Crapavetti and DECMate PCs, both were hailed as the future of computing. Oh and the started promoting Unix/RISC platforms as well. Oh and then the Alpha arrived and sort of made it a bit trickier to describe the product lineup. Confused does not even begin to describe the state of the customers or the sales teams.

I thought school was about learning the principles about how to do things like build, count, draw, read. I feel you are missing the point if you start training them on specific tools. Would a craft teacher agonise over using a particular make of lathe?
