A lot of people are betting their money on infinite growth forever of AI performance, compute usage, user base, subscription price.
I think cost will decrease forever.
I agree, but I also think as AI gets better we're going to see Jevons paradox in full swing, which might delay lower costs. We've seen this with Astra according to Tibo: https://x.com/thsottiaux/status/2097559315150426222
Cost will keep dropping, but the frontier will keep getting pushed. The whole "give me today's model 10x cheaper and I'm good" line is a fallacy. It isn't true now and it never will be for the top 1% of tasks, which will create the most economic gains.
