Block reward is now 6.25 btc, and fees reward is about 1.5 btc.
Every 4 years block reward halves, so in the next two halving block reward will be much less than fee reward, making it more and more irrelevant.
The 2140 is the date where it reaches 0, but it will be completely irrelevant in 12 years (3 more halving cycles).
