Microservices has been misunderstood in how they scale

I disagree with this statement. At that complexity level (be rewrittable and redeployable within 2 weeks), there will be an absolutely enormous set of microservices for any non-trivial application. Maintaining such a large set becomes a monumental challenge for local development in any company with more than a handful of teams.
Furthermore, I'm not convinced that all problems can be decomposed down into rewrittable-in-2-weeks chunks in a truly clean way.
Also, infra like email service, payments etc can probably fit into a 2 week rewrite.. but core domain is usually more complicated (since it's less well understood)
I've generally had more success with few, chunky services... The few times I've worked with teams that had a large number of small services, it never ended well (in one case, a 40 member Dev team - groups of 8... Ended up with each team maintaining about 3- 5 services)..
To me, micro services is more about scaling teams... Other than that, They seem to cause more tech problems than they solve.
Otoh, what do I know... There was some Uber talk where they had thousands of services...
