Apple announces MIE, then Intel and AMD say they have something similar except they don't actually have something similar, only plans to eventually implement it, but they're advertising it as if they do already have it. That sounds like super blatant "panicking to copy Apple" to me.

The submission title goes "Intel and AMD standardize ChkTag ..." but the actual text says "Intel and AMD are working together, along with their ecosystem partners in the EAG, to address the need for memory safety. They are creating a unified specification ..." (emphasis mine). They don't even have a specification yet, let alone an implementation, but they want to make PR waves about it already. This is so funny (and sad).
