Timeline confusion from Weyland's TED bio & W.I. site

Two different items I found odd. First, from Peter Weyland's TED bio: "Sir Peter Weyland was born in Mumbai, India at the turn of the Millennium." "In less than a decade, Weyland Corporation became a worldwide leader in..." This throws me off a bit, because Pearce looks his age [44] in 2023. Clearly he's not 23. Even if he had an accelerated aging disease, he doesn't act 23. And then on the Weyland Industries site, it says "CELEBRATING 50 YEARS OF BUILDING BETTER WORLDS." That would place the date of the Weyland site [in design fiction] no later than 2073. I thought the Prometheus was launched in 2082 & makes contact in 2085, but not sure if those dates are confirmed. Thoughts?
