the difficulty of bitcoin will also increase and no matter how good your mining hardware, it will hard to get a big reward. I don't think that for waiting 100 years, we still live in this world and maybe our great children that will mine the bitcoin until it's all mined. the technology will always grow and there will be a new hardware to solve the difficulty of bitcoin but like I said, the difficulty of bitcoin will increase too.

I see many people are confused with the basic facts included OP, all this is pre-determined and we can not have 21 million BTC tomorrow or for ten years. Approximately around the year 2140 last block should be mined (if bitcoin survive by then ), but almost 99% of BTC will be mined around the year 2032, so it is some 14 years from now. This is something what we need to focus on, that 1% of remaining coins and 100 years future event for those of us who live today is completely insignificant.

while some people think to double or not to double the price of bitcoin, others do not wait for 2022 to double the price, if it will be doubled every year the next 100 years it will be enough for us.

According to many sources for information. By 2140, the number of bitcoins in the world would reach 21,000 bits. I think from now on; maybe the bitcoin will not be as popular today, there will be new coins to replace them.
