I mean that's 4 companies though, so we're like saying "Microsoft has something like 250 billion in leases"... But they are "worth" over 3 trillion and hold assets worth 2-3 times those leases. Don't think it's enough to sink those large companies, it's just general investing at their scale now I guess.

Personally I think they are all overvalued, but unless all their shit flops quickly, they'll be around in 10 years still.
