I suspect that you know absolutely nothing about cars and the technology that goes into cars. Especially today. Why do you think they connect a new car through a cable to a computer to find possible errors? Because it’s all mechanical? Tell that to all the French cars that comes into the shop with technology and wiring problems 
But if you still think that the technology in a car is indifferent and a car just is a metal box on 4 wheels, then maybe a television will do the trick. I think we all can agree on, that the picture etc. gets better and better through technology and that 10 years in this field of technology is somewhat equivalent to a lifetime in other areas.
ah, yes. You buy a new car so that your mechanic gets a better diagnostic tool. Gotcha. ?
a TV is the same thing as the car analogy. When it’s made it’s made as a finished product. Done deal. An upgrade (!) from 4k to 8k is purely a hardware thing - «Software not included».
That’s not how the Kemper works. And I adore them for it. As long as the hardware can support their ever evolving software, you don’t need a hardware upgrade. The software is the upgrade as far as sound and «tone» in the Kemper. There is no «hardware» tone in the Kemper as far as input > [tone] > output. (ad/da discussions aside: I don’t wanna touch that nest of killer bees... ?)
Now, if you said you wanted a Kemper with four fx loops and a battery powered option, then that would require a hardware upgrade. And I’d agree with your sentiment. ?
All IMO of course. ?
