Also applications written 30 years ago today were often self contained applications. Something you can test in a variety of environments as a reasonable proxy to the end user. Today with SaaS/etc offerings you have very different difficulty spikes. Imagine only rolling out an update once a year to 1B customers. Especially with all the big changes that might entail. I can't imagine the fear. Releasing often irons out small problems before they become massive problems. Or, at least, is a strategy to attempt that.
