Luxury is build quality: not just a list of features, but the care and effort taken in assembling all the parts into a car: tolerances, alignments, finish quality.

Tesla fails all, with frequent misaligned panels, paint bubbling, ill-fitting parts, etc. It has software bells and whistels, but shitty build quality for the hardware.

20+ years ago, we did a trade-off in the datacenter, replacing single piece of expensive hardware with multiple copies of cheap hardware, with software to patch over the deficiencies. That doesn't work as well when the product is a single piece of hardware.

With some smart software, I can run 3 servers at 50% uptime each, and get 100% uptime. I can't get one nicely assembled car from two shitty ones.
