Khmm Intel... A paper from 1995 describing speculative execution as :"Prefetching may fetch otherwise inaccesible instructions in Virtual 8086 mode." which makes Intel know the 'recent' exploits knows for just a shy 23 years. Why didn't they fix it? Who know.

How many papers regarding hardware security or similar topics were there 1995? I can't really estimate that from the top of my head. Would be interesting whether intel realistically has/should have known about that or that paper has been unearthed now that everyone looks at the subject.
