Main problem with infinity is it presumes we can do an infinite number of things. I used this criticism to solve Zeno’s paradox. It is application of Marx’s (Hegel’s) epistemological principle that the proof of theory is practice. Can’t prove theoretical infinity in practice , because we are finite beings . https://youtu.be/CSe3_8shCMo?si=6Q2zHFWzRlvdcMb0
