This sounds a lot like the old argument of developers not being careful about how much memory/cpu they use. Engineers have been complaining about this since the 70s! As hardware improves, developers realize that computing time is way cheaper than developer time. Users have a certain latency that they accept. As long as the developer doesn't exceed that threshold, optimizing for dev time usually pays off.
