Is Deckard a Replicant? Blade Runner 2049

The new movie Blade Runner 2049 doesn't exactly answer this question; Is Deckard a replicant?
This is a long debated question among fans with the unicorn origami, the logic being the implanted memories. The theme of implanted memories does appear, we still don't have any concrete evidence to the age old question.

Still we can speculate and from my point of view Deckard is not a replicant.

Here are my 2 cents:

I was never convinced from the evidence from the first movie as well. The premises is implanted memories of Deckard mean that he is a replicant. However In the first movie we know the memories that are implanted in Rachael are of a real person i.e. Tyrell's niece, where does Deckard's memories come from?

This could be someone who is not mentioned or it could be Deckard's own memories and since he is a Blade Runner his memories have been recorded by Tyrell Corporation.
Now why would they do that and why would it be in the movie.
Firstly we need to acknowledge that Deckard has been forced to do things against his will, like the job of killing the 4 replicants at the start of the movie. So he may had to give his memories since he is an exceptional individual.
Why would they show it in the movie? this could be to imply Deckard is a replicant or it could be just a cool shot Mr. Scott wanted to add.
It could mean that Tyrell had been manipulating Deckard through understanding his memories. By studying his memories Tyrell made Rachael in a way Deckard would be fall in love with her. Thus insuring her survival by not getting retired by him.

Moving to the sequel Blade Runner 2049 it is revealed that it was Tyrell's experiment to give replicants the ability to reproduce as it was discussed between Wallace and Deckard. He goes on to explain how his meeting with Rachael was premeditated by Tyrell to make sure Deckard falls in love with her and make the miracle baby.
Now there is an ambiguity to this logic as it can be argued that, would Tyrell want 2 replicants to make the miracle baby?
To analyse this we have to take into account that the events of the previous movie had Deckard killing runaways and if the purpose of Deckard was to make a baby it would be just logical to have a simple narrative for him to fall in love.
Not to mention these events are what lead to Tyrell's death and he was a highly intelligent being, he would go through unnecessary steps which would lead to his death in his experiment. Also it would make sense to have a hybird of human replicant as the miracle baby as it would have more chances of success.

Hopefully we would get another sequel soon and not decades later and would give us more answers.
Till then we could only speculate.
