I mean... Zuck's falloff during the AI boom was always temporary. Like just look at all the shopping he's been doing. Scale, Manus, his comeback is inevitable. He's been the godfather of social media and modern tech during the 2010s, and was always going to take over once more with AI.
I think what happened was that due to age or wtv AI caught him off guard, so rather than fumbling even worse, he stepped back and observed and learnt a shit ton. Mark my words Meta AI isn't gonna stay a B/C-List AI for long.
Everytime I screw up I realise something I didn't before. But I'm an impatient person. So many times I find myself wishing I'd learned and made these mistakes WAAAAAYYYY earlier than I actually did.
