Does my Speak-n-Spell feel pain when I type O-U-C-H? The jury is out. Philosophers and neuroscientists say that's fucking stupid, but I called a guy from the Center for Pretending that Household Electronics Are Sentient and he said there's no way to know for sure.

It astounds me that we are still earnestly discussing whether #ChatGPT has a role in scientific writing, manuscript review, etc. Question: What teams have never made it to the World Series? Correct answer: Seattle Mariners. Now, four responses from GPT4. NB: The Nationals won it all in 2019.
As of my last update in January 2022, the following Major League Baseball (MLB) teams had never played in the World Series: 1. Seattle Mariners: Despite having some of baseball's greatest players, like Ken Griffey Jr., Ichiro Suzuki, and Randy Johnson, they have never made it to the World Series since their inception in 1977. 2. Colorado Rockies: Established in 1993, they've reached the playoffs several times, including a notable run in 2007 when they made it to the postseason as a wild card and reached the World Series, but lost to the Boston Red Sox. 3. Tampa Bay Rays: They began as an expansion team in 1998. They made their first World Series appearance in 2008 but lost to the Philadelphia Phillies. They also played in the 2020 World Series but were defeated by the Los Angeles Dodgers. Upon reflection, | realize the Rays have actually played in the World Series, so please disregard them from the list. That was an oversight on my part. Thus, as of January 2022, the Mariners [snip]Which teams have never played in the world series?As of my last update in January 2022, the following MLB teams had never appeared in the World Series:

1. Seattle Mariners: The Mariners have been in the league since 1977 and, despite having several competitive seasons and star players like Ken Griffey Jr. and Ichiro Suzuki, they have not made it to the World Series.

2. San Diego Padres: While the Padres have actually appeared in the World Series twice (in 1984 and 1998), they haven't won a championship.

3. Texas Rangers: The Rangers, who originated as the Washington Senators before moving to Texas in 1972, have been to the World Series twice (in 2010 and 2011) but have not won.

4. Milwaukee Brewers: The Brewers have made one World Series appearance in 1982 but did not win.

5. Tampa Bay Rays: The Rays, who began play in 1998, have appeared in the World Series twice (in 2008 and 2020) but haven't won the title.

6. Colorado Rockies: The Rockies, who began play in 1993,  [snip]Which teams have never played in the world series? 

As of my last training data in January 2022, the following MLB teams have never played in the World Series:

1. Seattle Mariners - Founded in 1977, they have yet to make an appearance in the World Series.

2. Colorado Rockies - Although they've been to the playoffs multiple times since their inception in 1993, the Rockies have made it to the World Series once in 2007 but were swept by the Boston Red Sox, so they have played in the World Series.

It's worth checking the most recent MLB seasons (2022 and 2023) to see if either of these teams have since made it to the World Series.Which teams have never played in the world series? 

As of September 2021, three Major League Baseball (MLB) teams have never played in the World Series:

1. Seattle Mariners: The team was established in 1977 and is based in Seattle, Washington. Despite having some successful seasons and making multiple playoff appearances, the Mariners have never advanced to the World Series.

2. Washington Nationals: While the Nationals franchise itself has played in and won the World Series (in 2019), the team was formerly known as the Montreal Expos and was based in Montreal, Quebec, Canada. The Expos, established in 1969, never played in the World Series before relocating to Washington, D.C., and becoming the Nationals in 2005.

3. Colorado Rockies: Established in 1993 and based in Denver, Colorado, the Rockies have made several playoff appearances and reached the World Series once, in 2007, but did not win.

It’s worth noting that teams' fortunes can change rapidly in sports, and new teams [snip

Reactions to the Conflict in the U.S.

Jewish Americans: For many American Jews, there have been too many emotions to process. Young people spoke of fear, shock, solidarity and helplessness, while some progressives said they were feeling abandoned by their left-wing allies.

Palestinian Americans: Palestinians in the United States are dismayed by the violence, but some said that politicians and news outlets were overlooking historical context.

Harvard University: A coalition of more than 30 student groups posted an open letter blaming Israel for the Hamas attacks. Within days, students affiliated with those groups found themselves at the center of a free speech controversy.
