Isn't a 24-word seed phrase overkill? Is 12 words fine?

Just got my first Ledger, and it defaults to a 24-word seed phrase. AFAIK, it would take [a trillion computers, guessing a trillion times a second, for the lifetime of the universe](https://www.reddit.com/r/CryptoCurrency/comments/njpmqv/whats_stopping_somebody_from_brute_forcing_seed/gz8oyqn/?utm_source=reddit&utm_medium=web2x&context=3), to brute-force a **12-word** seed phrase. A 24-word seed phrase seems like overkill. While I will be carefully storing my seed phrase, I also plan on committing it to memory. I have some experience with this, and 12 words is doable. But I'm not so sure about 24 words. I'm considering making a 12-word seed phrase wallet, and restoring the Ledger from that. So, is a 24-word seed phrase overkill? Is 12 words fine? Is there something I'm not thinking about?
