The article's talking about running 32-bit applications in emulation, with a 64-bit native kernel.

> Then a rewrite of RISC OS for 64-bit ARM chips would require a 32-bit emulation layer for old apps to run -- and very slowly at that, when ARM chips no longer execute 32-bit code directly. A software emulation of 32-bit ARM would be needed, with perhaps a 10x performance drop.

The cost of simulating 32-bit ARM on 64-bit ARM is nothing like 10x if you try hard enough

So I have been informed, in some detail, over on Lobste.rs.

I am glad to hear it. I like this little OS and I want to see it survive!
