And that is a problem... why?

As far as I can tell, nobody besides miners running old and/or buggy
software lost money due to outsourced mining validation (please correct me
if I'm wrong-- I'm looking forward to Greg's post-mortem). The operators of
bitcoin.org seem to have freaked out and pushed the panic button (with dire
warnings of not trusting transactions until 20 confirmations), but theymos
was well known for using an old, patched version of Core for
blockexplorer.com so maybe that's not surprising.

As Bitcoin grows, pieces of the ecosystem will specialize. Satoshi's
original code did everything: hashing, block assembly, wallet, consensus,
network. That is changing, and that is OK.

I understand there are parts of the ecosystem you'd rather not see
specialized, like transaction selection / block assembly or validation. I
see it as a natural maturation. The only danger I see is if some unnatural
barriers to competition spring up.

outsourcing of full validation keeps growing.

Both side effects of increasing specialization, in my opinion. Many
companies quite reasonably would rather hire somebody who specializes in
running nodes, keeping keys secure, etc rather than develop that expertise
themselves.

Again, not a problem UNLESS some unnatural barriers to competition spring
up.

I understand you want to build an extremely decentralized system, where
everybody participating trusts nothing except the genesis block hash.

I think it is more interesting to build a system that works for hundreds of
millions of people, with no central point of control and the opportunity
for ANYBODY to participate at any level. Permission-less innovation is what
I find interesting.

And I think the current "demonstrably terrible" Bitcoin system is still
INCREDIBLY interesting.
