Will RandomX work on the old cell phones, via Javascript interface only?

The website says: "Fast mode - requires 2080 MiB of shared memory. Light mode - requires only 256 MiB of shared memory, but runs significantly slower"

If you want your website challenge to work on the cheap phone - slow CPU, with little memory, and when implemented in Javascript, you'd have to tune complexity way down. And when a modern PC with fast CPU and tons of memory tries to solve it.. it probably will take only a few milliseconds, basically being useless.

I don't know, I dont understand the details and your reasoning is confusing for me. My understanding is that the effectiveness of particular hardware is complex to predict; it depends on the sizes of the CPU caches and effectiveness at certain instructions, and the algorithm can of course be tuned in all sorts of ways. The Tor project is already using it so presumably it is working for them to some extent. More info here: https://blog.torproject.org/introducing-proof-of-work-defens...
