The manual is dead (or on life support) because of us. Enthusiasts clamor they want a manual option but when it comes time to buy it, they don't. It's the automotive enthusiast equivalent of virtue signaling. We all want to look like we want a manual transmission and are hardcore enthusiasts but instead opt for the dual clutch or automatic.

Porsche can make it work because the GT3 manual take rate is roughly 50% (and falling) but Lamborghini can not:

Lamborghini looked into manual transmissions for special editions of both the Huracán and Aventador. Porsche has proved conclusively to Volkswagen Group that there's a market for high-end sports cars with row-your-own transmissions. Specifically, the reintroduction of the GT3 manual (with more than a 50 percent take rate) and the surprise success of the GT3 Touring. The problem for Lamborghini is cost.

Even if it charged a $25,000 premium for, say, the Aventador, and offered 200 units, that $5 million would not come even kind of close to covering the cost of converting the Aventador's ISR seven-speed box from auto to manual. Also, because the Aventador is mechanically unique, there's not a properly sized manual lying around that Lambo could just plop in.
How about we place the blame where it belongs for the manual transmission dying? On ourselves for not buying them.
