[Blade Runner] Why don't they make... you know... robots?

Yea they would be a lot less fun to fuck but presumably they can still make robots, just the regular metal kind, that could do most/all of the work, and just use replicants for stuff that needs programming to complex for robots or... you know like... genitals. 

This solves the problem that you need to tank grow replicants and that takes a long time plus... it would take longer to make them via fucking... like a lot longer.

It's a tale as old as time really.  It was all a result legislation and work from lobbyists.  Powerful people had the patents on vat grown parts and the processes involved.  They needed that technology to be profitable and they used the government to do it.  Giving out shares like candy to politicians and letting them create the legislation, tax incentives, and government funding to make the stock prices on all companies involved skyrocket.  Media and news organizations have the public eating out of their hands that synthetic grown replicants are the environmentally sound wave of the future.  Suddenly everyone is getting in on that action and nobody wants this technology to fail.  Regular robot part manufacturing just couldn't compete even if it made a lot more sense financially and ethically.  That leads us to today in 2049.  To even suggest we deviate from the way things are to a more sensible solution is shouted down as the backwards thinking of oligarchs of the past.

tl/dr: fat cats sold a lie to the public to make themselves rich and toss a few crumbs at people to help them along the way.
