[Harmless Teddy Bear]

Jobs publicly denied he was Lisa’s father for years, even though he took a paternity test in 1979 proving he was the dad. He was paying $500 a month in child support when he told Time magazine in 1983, “28 percent of the male population in the United States could be the father.”

No, the paternity test in 1979 did not "prove" that he was the father. It just raised the likelihood.

Yes the testing back then was generic. They could prove this beyond a shadow today.

In any event, Jobs should have upped the $500 per month to $5000 in 1984 when AAPL went public. Maybe he did.
