Tomorrow in this context is very near, and it is not any day in 2140 and after that, so Bitcoin miners will get both Bitcoin block subsidy (reward) and Bitcoin transaction fee that are all good for their mining business and its positive revenue.

In the future, naturally Bitcoin value and price will increase if its history repeats and this mean Bitcoin miners will get less bitcoins from their mining but get more $ in equivalent value. This will be a long future in 2140 and after that if Bitcoin continue its existence about more than one century in the future.

Bitcoin block subsidy from 50 bitcoins to 25 bitcoins then halved more every 210,000 blocks but its equivalent income for Bitcoin miners increases over time. Let's check back that 50 bitcoin in 2009 had less $ in value than 3.125 bitcoins in 2025 and it's the same change trend with Bitcoin transaction fees over years.
