Alternatives to S&P500? Foreign investments?

With the S&P500 now being overrepresented by AI-involved companies like meta Amazon Tesla and so forth what are safer alternative investments options while we weather out the incoming financial crash due to the irresponsible overvaluation in AI? I’m entering my 30s so I’d like alternatives that will return 4.5-7% realistically annually. obviously I have a lot of time on my hands still but if it’s like the dotcom crash in 2000, it will take 16 years before the market recovers… that’s a long time
