Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

but they grow very slow,they exist on places which propably suffer big damage from humans(latin america,south east asia,south and east africa..) i am rather sceptical about them,but it will also depends on when will humans go extinct, and what another extinction events will be present in future

They survived the Permian/Triassic boundary, they survived the K/T boundary, they survived every one of the minor mass extinctions between their appearance in the early Permian and now.

I'm just going to go ahead and directly quote the wikipedia page for cycads.
Quote:
 
Cycads are found across much of the subtropical and tropical parts of the world. They are found in South and Central America (where the greatest diversity occurs), Mexico, the Antilles, southeastern United States, Australia, Melanesia, Micronesia, Japan, China, Southeast Asia, India, Sri Lanka, Madagascar, and southern and tropical Africa, where at least 65 species occur. Some are renowned for survival in harsh semidesert climates, and can grow in sand or even on rock. They are able to grow in full sun or shade, and some are salt tolerant.

Does that sound like a description of a group that's on the edge to you?
I'm not a widely travelled person, I've never been overseas, but I've trapped around quite a of south eastern Australia. There are areas, and I am talking square kilometres here, where cycads are the dominant undergrowth species. As in you would not be able to pick out anything else if you were driving, you had to stop and look before you noticed anything else.

I'm not saying that they're going to bounce back to their former Jurassic glory, but they're definitely not going extinct any time soon.
Humanity would have to put in a concerted effort to wipe them out.
