“Cultivating doubt: why I no longer believe cultivated meat is the answer” by Tom Bry-Chevalier🔸

<h4 data-internal-id="Introduction">Introduction</h4><p> In this post, I present what I believe to be an important yet underexplored argument that fundamentally challenges the promise of cultivated meat. In essence, there are compelling reasons to conclude that cultivated meat will not replace conventional meat, but will instead primarily compete with other alternative proteins that offer superior environmental and ethical benefits. Moreover, research into and promotion of cultivated meat may potentially result in a net negative impact. Beyond critique, I try to offer constructive recommendations for the EA movement. While I've kept this post concise, I'm more than willing to elaborate on any specific point upon request.</p><h4 data-internal-id="From_industry_to_academia__my_cultivated_meat_journey">From industry to academia: my cultivated meat journey</h4><p> I'm currently in my fourth year (and hopefully final one!) of my PhD.
