This sounds very good but this date is light years from now and till then we will witness many speculations and manipulations of price. Fud will be better organized, hatters will find new arguments. I'm only not sure if this is going to be a spike or steady nice growth. Now prices changes 300$ daily, when reaches 10k we could see 1000$ daily changing of a price. This will open whole new possibilities for large investors. 
You have made a very good point here. According to me, we are going to see more spikes at least until all the bitcoin are mined out or bought by investors. In the coming years, the demand will be really high and at that time the overall supply would be even less than the present one which will definitely be the reason behind the rate that you told here. Bitcoin will touch this target of 25k dollars within next five years for sure.With this sluggish speed of confirmation, I actually don't expect that much.
Just hoping that in the upcoming years, atleast, something usefull will be added to bitcoin system, and blockchain have found the solution to its scaling problem.
