What is the sentiment of the following document towards the entity Tesla ? On November 16   Tesla  unveiled  its  long-anticipated foray into the $726 billion world of trucking: A heavy-duty  all-electric rig aptly named “Semi.” The truck itself is wildly impressive in our opinion—a 500-mile range  projected fuel savings of $200 000  and the industry’s most advanced levels of automation—but what excites me the most  really  is the opportunity this truck signifies: The start  as I see it  of a once-in-a-lifetime radical shift in our trillion-dollar transportation economy.
As I have written about before  we are currently entering a period of a rapid change in our transportation systems. And as I see it  it’s the innovator’s dilemma playing out in the wild: Incumbents like General Motors are moving too slowly to adapt to an all-electric future—wasting billions of dollars on stock buybacks—while upstarts like  Tesla   unencumbered by legacy business models  are forging a path into a clean  fully-electric  fully-autonomous future. (GM has spent almost $17 billion in the last several years buying back its stock  three times what  Tesla  has spent building Gigafactories—but I digress.)
I spoke with Perry at length recently regarding  Tesla ’s ambitions and challenges  the future of transportation  and his macro perspective on the innovation taking place right now in the trucking ecosystem. Below is an edited transcript of our conversation. (Full disclosure: Worm Capital is long  Tesla  and all views are Perry’s alone.)
Worm Capital: This week  we're seeing  Tesla  come out with their Semi  and clearly Elon Musk has talked about creating an all-electric  autonomous future. So  existentially  what does this mean for the trucking industry over the next 10  15  20 years? How do you see it evolving from what it is today to what it will be in the future?

What is the sentiment of the following document towards the entity Mikaela Shiffrin ? Mikaela Shiffrin makes it all looks so easy sometimes. For the world’s most dominant female ski racer  the trip from the starting gate to the medals podium is a well-trodden path.
Two difficult runs on Friday offered a harsh reminder for  Shiffrin  and the world just how difficult this medal pursuit could be  how difficult it will be to leave PyeongChang with a suitcase full of gold. Less than 24 hours after winning the giant slalom   Shiffrin  was back on the course at Yongpyong Alpine Centre to defend  her  Olympic gold in the slalom.
But at the Winter Games  things don’t always go as planned  and in  her  most dominant and consistent discipline   Shiffrin  finished in a disappointing fourth place  endangering  her  hopes of leaving here with multiple medals.  Shiffrin ’s total time of 1:39.03 was 0.40 seconds behind first-place finisher Frida Hansdotter of Sweden and just 0.08 seconds away from a spot on the podium.

 Shiffrin  seemed to know from the start of the day that something was amiss. Before  her  first run   Shiffrin  stood at the top of the course and vomited before launching down the hill.
“I just had this terrible feeling ”  she  explained later. “It was almost like a food poisoning feeling  like what is happening? I felt like my warm-up skiing was good  my turns and my free skiing was good. But when it came to putting it into the race  I was not like myself at all.”
 Shiffrin  has been open about  her  competitive anxieties and  her  ongoing battle with nerves. Last season  she  frequently became ill before races and sought the help of Lauren Loberg  a sports psychologist who works with the U.S. Ski and Snowboard Association.
On Friday in PyeongChang  in  her  best discipline and with an empty stomach   she  wasn’t  her  usual dominant self and clocked a time of 49.37 seconds  the fourth-best of the day’s initial runs. Entering the second run   she  trailed Switzerland’s Wendy Holdener by 0.48 seconds  not an insurmountable margin by any means.
“Rather than just focusing on the good skiing I know I can do  I was conservative ”  Shiffrin  said. “I was almost trying to do something special. I don’t need to do something special. I just need to ski like  myself  and it’ll be fine.”
Of the 2 900 athletes competing in the Winter Games  few are as dominant in their chosen discipline as  Shiffrin  has been in the slalom. In addition to the Sochi title   Shiffrin  has won the past three world titles  dating to 2013 when  she  was all of 17 years old.  She ’s now 22 and already has won 30 World Cup slalom events; only two female skiers all time — Austria’s Marlies Schild (35) and Switzerland’s Vreni Schneider (34) — have more. And  Shiffrin  has won the World Cup slalom title five of the past six years. (In 2016   she  missed two months of competition because of a knee injury but still won all five slalom races  she  entered.)
 She  had about four hours before  her  second run  enough time to nap  regroup and calm  her  nerves. Coming from behind is not a familiar position for Shiffrin  in large part because it’s such unfamiliar territory. This season  she  has competed in seven World Cup slalom races.  She  led after the first run in six  eventually winning five and finishing second in another. The only slalom  she  didn’t lead this season was Jan. 9 in Flachau  Austria  where  she  was second  trailing only one racer — Austria’s Bernadette Schild — by 0.37 seconds. She scorched through her second run and won the race over Schild by nearly a full second.

 Shiffrin  came to PyeongChang contemplating as many as five races. But weather wiped out two days of competition  forcing Olympic officials to shuffle and condense the Alpine schedule. For  Shiffrin    it  meant races wouldn’t be spaced out as much and  she  wouldn’t have as much time to rest and prepare for the speed events.

 Her  team decided to pull out of Saturday’s super-G race and haven’t yet made a final decision on next week’s downhill  though the combined is still likely. Having to open these Olympics racing the giant slalom and slalom on back-to-back days was exhausting in every way  Shiffrin said.

What is the sentiment of the following document towards the entity Chuck Grassley ? Sen. Chuck Grassley (R-Iowa) was besieged at a town-hall style event in Logan  Iowa on Friday with questions about President Trump. Mr. Trump won Iowa by almost 10 percentage points  according to the Des Moines Register.
 Grassley  is the chairman of the Senate Judiciary Committee  which is investigating Russian meddling in the election.
 Grassley  tried to emphasize that a deal on DACA needs to be reached before the March 5th deadline  saying "we've got to convince the American people that we don't make the same mistakes we did 30 years ago when we thought we had secured the borders because we did away with the magnet of people coming here to work."
According to KMTV   Grassley  said Mr. Trump's "sh*thole" remark "detracts from the very important issue that we got to get solved by March 5th ... it's better to keep to the issues  don't do anything to detract from the issues and bottom line  all people ought to be treated with respect."
 Grassley  will be holding another event in Sac City  Iowa  on Saturday morning  according to the Des Moines Register.
