It really depends if you think models have peaked or not, if they have peaked and now we are only going to see marginally better models I expect that harnesses will become better and costs will drive down, I expect much leaner orgs as people manage fleets of agents rather than employees.
I honestly think that there will be a mass tech grave as now one dev can do the work that required 10 before. We're already seeing lots of AI related layoffs (with mixed results today, but what about tomorrow ?)
I'm bookmarking your reply and am going to come back to it in a few years, if we'll be here :) Let's see 👀
