What I interacted with twenty years ago did less, operated on fewer device types, required a great deal more developer expertise and effort to create even simple applications. Commercial software was distributed largely on physical media with a buy it and own it business model (no freemium, ad-supported) and the development processes was largely based on those from the hardware world, i.e no agile. For most software all of that has changed and it comes with a cost.
