This just shows a total failing of your creativity or critical thinking skills if you can’t even put aside your current ideas to consider what other things can happen. You can’t consider another idea if you aren’t willing to put aside preconceived notions. You aren’t even saying the other system is bad or wouldn’t work or anything. You’re only saying you can’t even consider anything that isn’t exactly what you have now. It may improve your life or it may not, but you can’t even consider it because it’s different.
