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.
If Asian and African teamsarw weak in football that doesn't mean that don't deserve to play in fifa , if they are coming at level of qualification to play than why not giving them a chance to participate and show their skills .
You never know how things will be and how many new talents will be explored during this process.
