@kaia If you want something exciting beyond MSCI World or ACWI tracking ETFs and believe in a high tech future rather than a complete technological crash, then consider Nasdaq 100 or something like S&P 500 Info Tech in addition to the boring stuff.
Individual stock is never worth it. The market is always smarter than you. The only solution is buying the entire market. (Optionally SRI or at least ESG variants.)
