I agree.
Just by increasing slots to African and Asian countries it won't miraculously make them better.
We saw that with Qatar, every game they played it was painfully obvious that they were not at the required level to be there.
I guess this will become a bit more common in the next world cup, where more countries will qualify that don't really have the level we are used to see in the world cup.
It is not like additional slots are being given to Asian and African teams, not to improve their quality. This is a big misunderstanding. Additional slots are being given to them, because already there is an improvement in their quality. The previous allocation was based on the strength of teams half a century back, when Asian and African teams were quite weak. That is the reason why AFC/CAF were allotted so few slots compared to UEFA, for the 2022 Qatar edition. That mistake will be rectified for the 2026 edition.
Agreed, after all even though at this moment they still don't look any better, but over time they will improve and it is very possible that in the future African and Asian teams can compete even better in the world cup. Also, with this additional slot, wouldn't that be a great opportunity for the better teams to be able to get easy points for certain matches.
So yeah, I think there's nothing wrong with adding a slot like this, because at this moment Asian countries have also developed a lot and even though their football still can't compete further but at least, by being the host then that too will increase their income as well.
