It's not surprising that you only hear about Waymo in the news when something goes wrong. That doesn't mean it hasn't been extremely successful, which it has by any objective measure, other than profitability at least in the short term. The tech works.
As many have noted, the problem is largely Byzantine zoning regulations, NIMBYism, and a "vetocracy" system that makes it extremely hard to build housing in so major metropolitan areas. For example, NYC likely needs at least half a million new homes to keep up with demand.
This is a very poor comparsion. Sure, many companies went bust around then. But many didn't. Plenty of real value was created by companies doing real useful things.
A particularly absurd case of environmental review delaying a much needed project is congestion pricing in NYC. They are actually going to review the environmental impacts of a system that will decrease the number of cars on the road. What are they even reviewing?
BQE and Cross-Bronx Expressway definitely not. Building highways through cities is extremely damaging and exist only to ferry suburbanites into and out of the city. Moses wanted to build a highway through Greenwich village. That would have been devastating for lower Manhattan. Intra-city Highways destroy the very vibrancy required for them to adapt and change.
Brooklyn Battery Tunnel? That is a good project. Connecting different areas across bodies of water is good.
In this study, mRNA boosters were highly effective against infection with the delta variant but were less effective against infection with the omicron variant. However, these boosters led to strong protection against Covid-19–related hospitalization and death due to both variants.
We vaccinate in order to prevent severe disease, hospitalization, and death. The original vaccines, per the link you shared, are extremely effective at this.
Because there is no need for an updated vaccine. The original vaccine (especially with a booster 6 months after the second dose) is extremely effective at preventing severe disease, hospitalization, and death for all variants of SARS-CoV-2. (Alpha, Beta, Delta, Omicron, etc)
