> "the microsoft office suite for instance slows down every generation despite only having minor improvements and not actually being that different now than from 95" I can't comment on most of the Office suite, but Excel evolved quite a bit since 95. Tables, PowerBI, Apps for Office, etc... If your needs are basic enough then even VisiCalc will do the job, but new features do make an impact for more demanding users.
That's not the point though. The example given in the article was Google Docs which has the same UI paradigm to Word. Under the hood it's massively different obviously with real time collaboration and constantly up to date syncing. So, the reasoning is that UI is fundamentally the same (or worse if not done right) to native UI from the 90's, yet it hasn't had a massive speed increase which seems wasteful. But modern…
Evolution of a UI isn't as important as evolution of the features the UI exposes. As for whether it feels any faster, depends on what you're doing. To give an example, Excel functions can be calculated using multiple CPU cores, which AFAIK wasn't a feature of Excel in the 1990s. You'll only see that speed up if you've working with a large enough volume of formulas. Measuring speed by UI speed alone doesn't get you very far.
All that being said, you won't find me disagreeing with the fact that desktop apps are bloated (web apps even more so). I've experienced responsive desktop apps running on a 7.14MHz CPU. The fact that we've thrown away most of the hardware improvements since the 1980s should be clear to anyone paying attention.
