If the hierarchy is saying "it's time for GenAI", you have the option to participate in a way that raises your profile and positively influences the company (involving politics), if you hate GenAI so much you can leave, or you can stay silently and opt out of the process. These are all choices. Personally I'm fine with my VCs making strategic decisions since they trust me to make technical decisions. So we can do GenAI, we'll just do it in a way that works and is sustainable for the codebase.
You should realize that as a technical person your domain is not business strategy. Similarly I'd be shocked if any VC ever came in and told me "to use PostgreSQL" or some other nonsense. If you want to be the person deciding what we build, go into Product.
Given that, I'm not sure what your message is in response to. I will say that 'learn to parcipate in the hierarchy' and 'everything is a choice, just quit!' are hardly solutions at all, and read more as truisms.
I'll add that I'm not sure what VCs have to do with anything here, though as someone who formally took VC funding, I wouldn't want them making technical or strategic decisions on my behalf, and I suspect the majority of founders (and others on my cap table) would agree.
