Maybe but despite the mention of Afghanistan not being a real nation but land populated by various ethnic groups who coexist but lack a national identity; there have been periods where the country was stable.
A lot will depend on the Taliban. Post 2001 they realised they had to change; to mellow down if they hoped to eventually regain power and be accepted. They also fully realise that they are under intense international scrutiny; Afghanistan is not as isolated as it was in the late 1990’s when they first came to power. If they can develop some level of understanding with the other ethnic groups: stability will follow.
To prepare for the future they have also already established links with China, India and Russia. My opinion is they couldn’t care less if the U.S. and EU doesn’t officially recognise them.
As for the neighbours; Pakistan naturally will play a vital role. A long border and a large Pashtun population in Pakistan; not to mention Pakistani fears of India being active in Afghanistan means that country will always be of strategic interest to Pakistan. Would be a mistake though to assume the Pakistanis have full control over the Taliban.
Another country vital to the overall scheme of things is Iran. Both countries share a long border and have links that goes back for centuries - natural that Iran wants a stable Afghanistan and will want to have influence there (like with Iraq). How many Afghans view Iran differs from how America does. For many years Iran provided refuge to Afghan refugees and together with other countries supplied anti Taliban groups at a time when the U.S. refused to do so. How the Taliban is able to improve relations with Shia Iran remains to be seen.
The future of Afghanistan could all go so many ways.
There is no script.
I just hope that after so many years of conflict some stability and peace comes to this land.
I recall some of my uncles tales of travelling from Europe to Asia overland via Afghanistan.
More adventurer than hippie, all you needed was a kombi / spare jerry can of fuel, a bunch of mates on a budget, a compass, and the spirit of adventure.
He still met locals with beards and guns, but that was their world in the early 60's and yet he and his mates still made it safely across this region with stories to tell.
Trust that world returns for a future generation to enjoy and for the locals to reap the benefits of trade and interaction.

Ps - In the mean time the West will ponder how to tackle complex international contingency's that actually have an end game.
