  Many approaches have been proposed for early classification of time series in
light of its significance in a wide range of applications including healthcare,
transportation and finance. However, recently a preprint saved on Arxiv claim
that all research done for almost 20 years now on the Early Classification of
Time Series is useless, or, at the very least, ill-oriented because severely
lacking a strong ground. In this paper, we answer in detail the main issues and
misunderstandings raised by the authors of the preprint, and propose directions
to further expand the fields of application of early classification of time
series.
