I regularly have conversations like this with friends, and it is one of the reason Izuku, from My Hero Academia, is one of my favorite characters. It's fun!

Bubble shield can be done with both basic Tk and advanced Tk but would work in different ways. Basic Tk would be just a simple pulse of TK to repel things. Would only work if the Meta in question was paying attention and might miss things if they aren't aware of some things

While Advanced Tk could set up a static field that repulses up to everything everything without needing to be micromanaged.

The power set growing as the generations grow always makes sense to me.
