Its less about minimal amount of work and more about what you can get away with. You now tolerate less performant and lazier solutions because hardware is so much faster and you can now get away with it in front of your users. For example, microsoft excel feels no faster or more special or does anything more really than the version I was using in 1995 which was served on cd rom or even floppies, compared to a couple GB over the air download for an application that today still takes time to open up on modern hardware. MS gets away with this because users expect the same features as 30 years ago and also expect excel to remain as slow as it felt 30 years ago. You could be lazy back in the day, but you still had to ensure your program was small enough to actually ship on physical media, and could actually run on this hardware thats several orders of magnitude slower than what developers expect users to be running today. So you can definitely get away with being even more lazy, less optimized, less performant, and still have a job shipping 'functional' software today, than what the constraints were decades ago.
