Hii...@crypto.piotr , first a fall, its awesome your giving all the rewards of the post to someone who needs it, lovely.
Now, about the question your raised.
See, I don't really think having kids is good now, because we are facing a ecological crisis - there will be a world without air, water, greenery and I highly recommend everyone however harsh it may sound to not bring another being to suffer in this world. I am speaking really seriously. Please consider adopting a kid instead.
Next on kids future... I can't speak on this much, but you have to believe in love. If you grow your kids spending quality time with them, exposing them to the outdoors, doing fun activities with them, you will bond with them!!!
Please don't bother weather they will take care of you in the future, that's upto them, but our focus is to be the best parent raising kids with good values. Please believe in atleast relationship, if not humanity, I am sure kids will love and take care of their parents, if they don't, they don't.
Our job as parents is instill them values, prepare them to be the bestest them that they can be. But don't you think, parents themselves don't spend quality time with their kids, they themselves are hooked to technology, let their kids get hooked onto technology, don't notice kids, don't understand their kids, all because they are not spending quality time with them?.
It's believe we are not raising kids properly and being good role models that kids become like what you said. Teach them to love, be responsible, independent, brave, proactive, humble.
Have fun with them - play, read stories, crack jokes, do some outdoor activity, have dinners together, talk with them. Establish a bond!!!
Anyway... But I again emphasize, please don't procreate now, because the world is already finding it difficult to sustain itself. Let's work to improve soiety, ecology and enjoy life instead.
