In 2032, which I hope to be around to see, we're already 99% done with production and BTC per block is pretty close to current earned transaction fees per block. So I guess the dynamic in 2030 isn't much different than the subsequent 100 years.
In bitcoin there arent any fixed years. These are approximations based on the assumption that difficulty changes every 2 weeks. In reality difficulty changes faster so those dates will move back by a lot. 2032 = a lot sooner than 2030.
