Bitcoin did increase its blocksize and throughput. It about doubled it in fact.

Yes, people don't realize that we don't want bitcoin to be agile, move fast and break things. We want it to be well considered, move slowly, and be safe and careful. Similarly, it aggrivates me that people complain about how "congress moves too slow, there's too much deadlock". We shouldn't want lawmaking to move fast. Like bitcoin, it should be slow, methodical, and careful. The problem with US congress is not that its slow, its that it is massively corrupt and opposing sides rush to put things together and then don't cooperate on improving proposals into a considered compromise. Slow compromise is what we want, not fast stubborn corrupt legislators.
