It’s a trade off. Would you rather have more software with more features or less software that runs fast and efficiently?

The market has clearly spoken in favor of the former.

After all, the goal of engineering isn’t to produce some abstract beautiful art but rather to create something valuable for regular humans.

Also the car and building analogies are poor because they are essentially the same design that has been optimized for decades. Indeed the only “new features” in cars are usually software driven and probably just as inefficient.
