Thanks, I'll give it a try. I had read about it and about Coase relatively recently but I had skipped the subject, mostly. I think it's a very interesting subject, especially for our field, to be honest I didn't expect for the consolidation at the top to happen so fast (~10-12 years) and at so grand a scale, 9 of the biggest 10 companies by market cap are tech companies (I'm including Tesla here).
