Predicting the future is hard, it's difficult to know what is really a permanent game changer and what isn't except in hindsight. Most things, like the ones you cited aren't so our prior should probably be that drones aren't but real permanent game changers do exist. Nobody fights with spears any more and nukes took direct great power wars off the table.And I’m sure that adequate means of suppression will appear sooner or later, either through counter technology or finally adapting ground combat doctrine to match the pace of 21st century informatization warfare.
Artillery, machineguns, and spotter planes didn’t keep people who really wanted to kill each other permanently confined in trenches for the entire 20th century.
However even if drones aren't that level of game changer, they could still affect battlefield realities significantly on a permanent basis. Just look at how different infantry tactics today are compared to tactics of 200 years ago. Infantry concentrations really are just permanently lower because adequate means of suppression of automatic weapons never developed. You never see hundreds of people packed shoulder to shoulder in battles now. Maybe drones also will not really have a highly effective means of suppression and the result is that tanks and infantry tactics will have to evolve to meet this new reality.
Personally I am pretty disappointed there is no T-14 or upgraded Type 99A style 50+ ton tank but PLA is training to win wars not to satisfy people's aesthetics so it is what it s.
