May be you are right it will take long time to achieve the price of $2k and I don't see it happening in this year and even if it touches that price in next year, it will not stay there for long term.
I think it will take 15 to 24 months for the bitcoin to rise to $2000. After the introduction of SegWit, it could be faster.
Yes we can expect that price after 2 years from now, as bitcoin is really taking long time even to touch the price of $1k since long time, so our first target should be to see the price of $1k.
