Dumbing down taxiing to a beam of light off a wingtip coincides with automation to make flying so simple a caveman could do it but it looks like it is going that way so why not. I'm so glad I'm retired.

If your idea of flying is that it should be more difficult in order to be safer then I'm glad you're retired too.
