Millennials will never forget Bill Nye — the lanky scientist from VHS tapes they’d watch in elementary school when their teachers were too hungover to do their jobs. He was the highlight of every young person's American education.

Yet as they've grown, Bill has grown too. These days, however, he’s no longer playing it safe behind bleached lab coats while focusing entirely on the cushy subjects appropriate for pre-pubescent children. Instead, the '90s nerd is now voicing his professional opinions on controversial subjects like the science of sex and drugs.

“Sex is all people think about,” Nye tells Inverse, assuring us that cuddling, hook-up apps and sexually transmitted diseases will likely never go away.

Humans aren’t good at a whole lot of things — we can’t beat computers at chess, regenerate body parts, or even convince the whole population that the Earth is round — but we can bump uglies until the cows come home. That’s why the technology that helps us find fuck-buddies and spread our herpes is here to stay.

Nye’s scandalous stances have pissed off a lot of his followers. In his Netflix TV series, Bill Nye Saves the World, he tackles sexual subjects like gender identity and gay conversion therapy, attracting the rage of the right-leaners.

For example, Nye approaches gay conversion therapy — a homophobic practice that aims to cure the queers of their gay-ness — with a cartoon in which a vanilla-flavored ice cream cone tries to “convert” more exciting flavors.

In a song and dance segment titled “My Sex Stuff,” Nye invites a guest to broach the subject of fluidity of sexual and gender identity — by literally singing the praises of butt stuff.

Nye is now beginning to weigh in on the scientific promise of marijuana. “People [in reputable studies] get very well-documented benefits from marijuana use as a medicine in various forms. So this is worthy of investigation,” he tells Rolling Stone. “Scientific study is of great value, and I think marijuana is worthy of scientific study.”

Nye even criticizes Jeff Sessions for his narrow-minded statements. “Let's not criminalize it,” he says. “Let's tax it! It's a crop that we can raise and monetize.”

This woke TV scientist isn’t the same one we grew up with. Let us say our goodbyes to the agreeable Science Guy of yesteryear. He’s long gone, just like every other piece of our childhood innocence.
