Yeah, economics is weird like that, and we should probably push as hard as we can to make sure things are as fair as reasonably possible. I've got no problem with trillionaires or megacorps if the system in which they operate is fair. One thing AI is enabling is systematic uncovering of fraud and waste - we'll be able to scan omnibus bills and find corruption, track politicians, interact with the system and communicate at higher levels than before, and there's a shot at AI empowering and enfranchising people more than they've ever had a chance at before.
If AI coding alone reaches its potential, then a whole class of corporations lose their leverage in the market. In 10ish years, following moore's law, phones will have enough compute and storage to trivially run your own local search and curation of the internet. Sophisticated search engines that outclass anything currently on the market, working in tandem with a personal local privacy respecting agent. That decentralizes things in such a significant way that Google and Apple and all the gatekeepers lose their ability to manipulate and distort.
20 years from now, even if we're somehow just stuck at the current levels of AI, your personal compute will be totally sufficient to provide all the curation, moderation, proactive interaction, and search capabilities without ever having to deal with ads or bots or cloudflare.
There are lots of dangers, and ASI could wreck us, and militarized AI could be a doom scenario, or there could be overbroad stupid regulation that puts control of AI in the hands of a few corps or a government, but there are lots of bright future possibilities, and I don't see any indications that we're directly headed toward any particular doom.
