Earlier quoted context omitted.
Ethereum is already a lot faster than that, and will probably get to Eth2.0 with sharding and PoS in the not too distant future. Then your ETH transactions will be blazing fast, secure, and cheap as chips. Of course, they've been saying all of that is not so far away for a couple years now, but we will see. I'm tentatively optimistic.
Ethereum is still on proof of work, so it has the same problem as bitcoin. If they made confirmations take 1 minute instead of 10 minutes, that just means their confirmations are 1/10th as reliable as Bitcoin's confirmations. Nothing was solved there. And PoS has been "not so far away for a couple years now" because they keep finding problems with it.
This argument is tired. There is no rule that dictates that the same amount of work or stake is equal to the same amount of security across different coins. I trust ETH transactions just as much as I trust BTC, and there are others that I trust equally also.
And now that BTC costs more in fees, their solution is to move to less secure off-chain layers. I'll take on chain ETH, monero, BCH, and a few others any day over a low security off-chain solution like what BTC offers. I may hold BTC, but I'm not buying it, and I'm not using it.
