The fact that I still get plenty of use out of a 13 year old laptop should answer that question.  Computers are getting better but only incrementally.  They're packing more transistors onto each die, but they're not really increasing the density by a significant margin, which is why the big stuff now requires water cooling.  Regular CPU's have plateaued, GPU/NPU is a parlor trick of reducing functionality and packing more cores onto the die, but again, not at any increased density.  Quantum computing is perpetually in a state of "almost there".

And I don't think most people need to care.  There's no requirement for ever-increasing density.  Hitting a wall could actually be beneficial.
