Who is the GOAT of chess?

Transport him to 2025 and he'd crush everyone without breaking a sweat.

I think all the greats - Morphy, Alekhine, Capablanca, Fischer, Kasparov etc would all be around the same strength as Carlsen, had they all been born in 1990, with the same access to theory, databases, engines.
They'd all be Super GMs. You simply can't compare players from the pre-computer era with modern players. It's apples vs oranges.
