I've got advanced degrees in engineering. So, yeah, I understand exponentials, the natural logarithm, and curves pretty well.
Take a look at the US on this map. Tthen look at China, which I think is fake data - but it does show a flattened curve:

The US is still rising like a rocket.
Texas is rising fast, too. It is about 3-4 weeks behind NY, but is heading in the same direction. Texas may never get as bad as NYC because it does not have crowded subways and buses. But Texas has no flattened out either.

29Mar2020 positive tests 2,552 negative tests 23,208 deaths 34 total tests 25,760
30Mar2020 positive tests 2,877 negative tests 33,003 deaths 38 total tests 35,880
31Mar2020 positive tests 3,266 negative tests 42,992 deaths 41 total tests 42992
(2877-2552)/2552 = 12.7% increase
(3266-2877)/2877 = 13.5% increase - mild, not exponential
We are beating this thing in Texas! Death rate in Texas for COVID-19 still very low and not growing.
Since 25 March Daily deaths 6, 5, 4, 7, 4, 3
I think a reasonable person could conclude, from the deaths, that it isn't a bad trend. As for the increase in cases, well, we have only been testing patients with obvious symptoms, which I believe you people call a biased sample. Until we randomly test a representative sample of the population, we really can't know if the case rate is increasing or not, can we?
I think the hospitalization rate would be a better variable, compared to hospitalizations this time last year.
I'm willing to concede we need two more weeks of data to know what happened to people infected in the last 2 weeks, but it doesn't look bad so far.
