The First Ammendemnt protects your right to not participate in reciting the pledge of allegiance:
In 2006, in the Florida case Frazier v. Alexandre, a federal district court in Florida ruled that a 1942 state law requiring students to stand and recite the Pledge of Allegiance violates the First and Fourteenth Amendments of the U.S. Constitution. As a result of that decision, a Florida school district was ordered to pay $32,500 to a student who chose not to say the pledge and was ridiculed and called "unpatriotic" by a teacher.
In 2009, a Montgomery County, Maryland, teacher berated and had school police remove a 13-year-old girl who refused to say the Pledge of Allegiance in the classroom. The student's mother, assisted by the American Civil Liberties Union of Maryland, sought and received an apology from the teacher, as state law and the school's student handbook both prohibit students from being forced to recite the Pledge. reference
You might suffer some immediate consequences from ignorant people, but courts have repeatedly upheld that this is protected by the First Amendment. Even the current Supreme Court would have a hard time justifying overturning this precedent.
You could even argue that choosing not to participate is a highly patriotic act, as an exercise of your Constitutional rights as a citizen.
Maybe the true Everett was the cherry picking we did along the way.
A zoo used to be little more than animals in cages put on display for public viewing. The idea is a modernization of the menageries that used to be kept by nobility, and the first public zoos were just these menageries opened to the public:
Until the early 19th century, the function of the zoo was often to symbolize royal power, like King Louis XIV's menagerie at Versailles. Major cities in Europe set up zoos in the 19th century, usually using London and Paris as models. The transition was made from princely menageries designed to entertain high society with strange novelties into public zoological gardens. (ref)

It's not just the amount of time. The portable electronics market and the electric car market both settled on lithium batteries, which created a huge demand for that particular technology. Over the past 2 decades there has been a massive incentive to develop smaller, denser lithium batteries.
There may be interest in developing other battery technologies, but nothing like the amount of money and effort being spent on lithium batteries.
