Come on, the whole new world discovery had bad roots. It was to expand to find wealth and get fat. Colombus isn't responsible but the big picture is that the ~amazing discovery resulted in massive genocides from north to south america.

Colombus wanted to go to the spice island and they would have traded with the people there.

And also what's your alternative? For the different parts of the global never to come into contact?

You could throw shade at pretty much all human exploration because most of it was done to get more resources of some kind.

Oh yeah, I'd have zero problem not knowing about cultures that were already living their own live minding their own business. You know researchers today have a rule to not pollute or disrupt ecosystems they study. Constrating.

Hm. The amount of starvation, disease and hardship in the old days are not to be wished on anyone. The world coming into communication has its upside too.

Granted, the New World suffered grievously by contact - an estimate 100M dead from diseases they were unequipped to handle. So there's that.
