Programmer time is more expensive than computer time.

That might excuse inefficiency if all of these things were true:

• The programmers (or their employers) were buying new computers for all their users
• The new computers were fast enough to keep slow software from wasting users' time
• The electricity to run them was free and without pollution
• The resources consumed and waste produced by that upgrade cycle had no impact on the environment

What's really happening here is that producers of software are making things cheaper and easier for themselves by shifting and multiplying costs onto the users and the environment.

The amount of waste is staggering. It's part of why I haven't enjoyed professional software development in years.
