The big takeaway here is that Google's (and advertisement in general) dominance over the web is going away. This is because the only way to stop the bots is with a captcha, and this also stops search indexers from indexing your site. This will result in search engines not indexing sites, and hence providing no value anymore. There's probably going to be a small lag as the current knowledge in the current LLMs dry up…
OpenAI goes through initial cycle of enshittification. Google is too big right now. Once they establish dominance you will have to see 5 unskippable ads between prompts, even for paid plan.
I solved user problems for myself. Most of my web projects use client side processing. I moved to github pages. So clients can use my projects with no down time. Pages use SQLite as source of data. First browser downloads the SQLite model, then it uses it to display data on client side.
