Naw ETh scaling plan is 1 million tps:

Bitcoin scaling plan is the LN+(sidechains):
Each channel can process about 500 tx per second(a channel is when a node opens a connection with another node. This can be done many times with same nodes). LN is now limited by the number of nodes.

Also transaction does not mean ever day:

But yeah Steem has this in the bag. All of these scaling plans are not on chains. A decentralized social network can't work off chain otherwise how can you read the data?
Steem has some much potential-I can't wait :)
With all those SMTS steem will be even more powerful :)
