Does relearning up-to-date programs make it harder to learn new ones?

I've noticed that they keep changing the design, theme, configuration and position. These new features get in the way of those who are learning and make it difficult to understand the program.

Instead of creating something classic where the teacher knows where the button is to help the student, they change everything to make it kawaii.

the teacher will have to study the program every year, instead of taking the time to study other programs, they'll be stuck studying just one area.

for example, i loved office 2003, but they ruined the design by changing the entire design, button positions, settings, UI, UX, colors, etc.

they really have no love for what's old and working and want to appeal to the new smartphone audience, since those who use PCs are users of another niche and not the smartphone niche, where everything has to be a pretty UX, UI, etc. and on PCs everything had lots of options, buttons, settings, positions, bars, panels, etc.

we can see this in a number of programs, which have "improved" but only worsened in the eyesight of those who used a pc in the 2000s with windows xp.
