The same world that we've been living in since humanity gathered into groups for mutual defence.
These days it's the mighty dollar, before that it was gold or silver, before that it was trade goods and food, and before that it was just services exchanged. Humanity evolved a pretty selfish creature. As a species, we don't do something for nothing. Tesla and the rare few who seem more interested in doing something for nothing are...abberations. Good abberations, to be certain, but an abberation to be certain.
I honestly do not think that Tesla would have fared better in any time period. An idealist, no matter how good at what they do, with a pragmatist running point tends to get buried. Frankly, I think it's a miracle that so many of his inventions did survive.
If he had been given the respect and attention he was due, I think that it would be a very different world to be sure.
