I dunno. I kinda agree with him with some points
I've wrenched plenty on older cars, and having a newer car 've hooked my laptop up to it to reflash modules or troubleshoot things. If you know what you are doing on a PC it is pretty easy. I've used Forscan to troubleshoot some heated seat issues i was having on my '14 Taurus, as well as reprogram modules, or unlock navigation and make it functional on the stock head unit. You can pull up PID's on all sort of things in the car to see if they are working as intended. It's a great tool if you know how to use it.
It still is a hell of a lot easier to replace a water pump on a fox body than it is on virtually anything new these days. The issue is space...you just can't get to anything. I've seen so many repairs that require dropping the engine down from the body to make the repair. How many people are going to do that in their driveway on a sat to fix it.
