so they anticipated the hard fork, to january instead of the planned march
also if it will double every two years for twenty years it mean a maximum of 256MB, which is around 1000tx max per seconds, still far below what it is visa right now
"Do you even math?"
I can't even figure out how you got 256 MB? 2^8 is 256; however the number will double 10 times according to Gavin. I'm surprised.
Update: That explains it.
Well, let's see the sequel, it seems need more information.
Does that mean in 20 years after it starts doubling the blocks will be 8192 MB, which is 8.192 GB per block?
Have I done my maths right?
8 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 8192
To keep it simple I'm not considering the difference between mebibytes and megabytes.
What? that's too much right

He told doubling every 2 years, so every 2 years increased 8MB. The parameters will implement next years(2016) and then in 2018 increase 8MB, so 8+8=16MB.
You means 20 years after starts. Start from 2016 and the end is 2036.
8MB(2016) + 8MB = 16MB(2018) + 8MB = 24MB(2020) + 8MB = 32MB(2022) + 8MB = 40MB(2024) + 8MB = 48MB(2026) + 8MB = 56MB(2028) + 8MB = 64MB(2030) + 8MB = 72MB(2032) + 8MB = 80MB(2034) +8MB =
88MB in 2036.CMIIW.
No, it does not seem much. You're mistaken with your calculation. Do you even know what the definition of 'doubling' is?
To make twice as much. Multiply by 2.
So it is not 'add 8MB every two years for twenty years'.
In 2036 we are going to have 8192 MB blocks. Since it is also acceptable to use 1000 (MB = GB) instead of 1024, we can say that we are going to have ~8.2GB blocks. This actually might probably not be that much in 20 years. We can't really tell now. If we assume that our current tps is 3, we are going to have a tps of 24, 576 in 2036. The number doesn't seem that bad, however more is required for mainstream adoption.
Calculation: 3 x 8 x 2^10; 3 tps times 8 MB blocks (2016) times doubling ten times.
