I was debating Telegram vs Matrix groups with an Ethereum developer,
And he said "We use Telegram because Matrix hasn't lived up to democratizing things as promised"

You're mixing up democracy and decentralization.  To quote nostr:npub1haqmanygx8nnzhv6n8ur7ytfpxvkqhamt9r5yd8sjxnpvy7utxgs89cvpg,
"Democracy is literally a 51% attack on decentralization"

Ethereum switching to democracy (proof of stake) has not really brought about the speed or cost fixes promised.  But it has introduced the new issue of the KYC exchanges having majority staking power, so they could be forced by the government to censor or steal.

One day man, you'll wake up and see that democracy is bullshit, as your fundamental human rights shouldn't be subject to the mob's decisions.  But unfortunately that day may only come because the vote will be against you.
