Nah terrys38, it's just a couple extra machines. Doesn't mean our work is pointless, just different. Probably not that deep.

Have you noticed this same thing in other parts of life, not just cars? It's like how my grandma uses a recipe book but still checks online for tips. We always chase the new shiny thing and ignore the old stuff that never lets us down. That trusted timing light with a name shows how some tools just become part of the team. The trick is probably using both, so the new tech proves itself without throwing out what already works.
